I like chunkier scrollbars. Fuck the tiny disappearing scrollbars where you need to mouse over... somewhere.. to maybe be graced with its presence, only for it to be 1px wide for some reason.
Also fuck the endless scroll, especially when you already know what you're looking for is on page 4 because you had to reload the page for some reason but the infinite scroll didn't save your position and you have to go down (without an actual scrollbar) only to "load more" 3 times until you're (maybe) on page 4.

I absolutely hate those scrolling number pickers, like on alarm apps. Just pop up the numpad and I can enter a time in 2-4 taps, not 2-3 coarse scrolls of minutes, a fine scroll to the minute I actually want, then repeat that process on the hours.

Colorblind people exist and should be able to use the site. At least, based on my real experience, this must be an unpopular opinion amongst UI folks glares

Scroll bars are way too fucking thin now. When I have an app on one monitor, and try to scroll it, I’m battling the move to the next monitor with the teensy tiny scrollbar.

I’m even someone that knows how to use the mouse wheel and page down keys. It still has its place and so many refuse to acknowledge that. Sometimes I can’t even tell where on the page I am because the scrollbar activated its Octocamo.

Any button that's grayed out should say why it's grayed out when you hover the cursor over it, or attempt to tap it.

Unpopular because most people don't notice at all, not because they disagree:

Bring back ellipsis to signal a new dialog instead of a complete action. E.g., a button "Save..." opens a dialog where you want to save, whereas a button "Save" saves it immediately

If it doesn't need JavaScript, it shouldn't have JavaScript.

If it doesn't need dynamic styling, it shouldn't have dynamic styling (especially if it makes other elements move around or become occluded).

If it doesn't need images, it shouldn't have images. When it does need images, they should be in an appropriate format and minimum useful filesize.

It shouldn't have audio. It doesn't need audio, and should not have it.

The hamburger button is an abomination, we need the proper menus back

• Stop removing the underline styling for links. It's not cool or sleek that you made things unintuitive to navigate by having the only indication be a slightly different text color, or a hover effect.
• I don't like emoji in text interface output. I don't need cute little sparkle graphics and yellow smiley faces and lightning bolts and rocket ships to tell me the operation was successful, to say nothing of environments where emoji aren't supported and it's just broken.
• Please stop trying to be cute or hip with your basic interface messaging. "We got you, we'll find those results you need. Just hang tight, OK?" "Oops, our bad, there was a little hiccup in the process..." It's unnecessary padding just like all the rounded corners everywhere. Exception if the entire app/site/whatever is specifically designed around being cute and friendly, but I see this all the time where it just feels out of place, disingenuous, and obnoxious.
• Custom fonts and nonstandard characters in usernames are an abomination. Show your personality and creativity in your graphical avatar and your profile, I'm happy to see it there!

I don't know how unpopular this is - I've never asked anybody:

Phone-optimised UIs suck, even on phones. One of the first things I do on setting up a new phone is tick 'request desktop website' in the browser.

Really big mouse cursor.

I don't have sight issues at all, but you spend more time tracking the mouse than you think. And after less than a day the real estate it takes up doesn't bother me.

Get rid of the tool bars. All of them. Menu, navigation, window decoration, cookie consent, status, tab and start.

They suck. We live in a 16:9-21:9 world, where it's bad enough in landscape. When it's in portrait, where half of the real estate is taken up by a keyboard, and that space really matters, it's almost worse. Letterboxing is dumb when it's black bars on a movie, I don't need its cluttered cousin on every application and webpage I'm on.

Vertical overlays or context menus can be enabled by default if you must, but give me shortcuts to do the even the most esoteric operation and I'll gladly learn them.

I don't know how this is an unpopular opinion after a half centuary of dealing with increasingly multileveled toolbars, but it must be because toolbars are not going anywhere.

If you have to have a toolbar, at least make it go away when you scroll.

UIs should strive to always be as customizable as possible.

Colors should be able to all be manually set by the user if they want to, rounded corners should be configurable, and the user should be able to overwrite icons and some UI elements if possible, but it shouldn't have to be on a per-app basis.

Instead, apps should ready system settings configured by the user and apply their theming unless the app is configured to do otherwise, again, by the user. Consistency by default unless you don't want it.

I can see why this opinion would be unpopular (maybe designers want to make their UI a very specific way idk)... but I like theming!!

Also, there should be a mode between dark and light mode that has black text but doesn't have a blindingly white background.

A lot of so called "dark mode" should be called "medium mode" or "gray mode". In my opinion "dark mode" is where the main colour of backgrounds looks more black than gray. Also all borders should be high-contrast, preferably brightly coloured lines, or medium-contrast for low-importance borders, but never low-contrast borders or borders without a line where it's just a change in background colours.

The modern trend for "flat" UIs absolutely sucks. There is no separation between element layers, so you can't tell where one windows starts and another begins when they are overlapping.

Overriding browser functionality because of designer preferences or shitty implementation of tracking or whatever.

Don't fuck with my scrolling.

Don't fuck with my ctrl clicking to open links in a new tab.

Don't capture window keyboard events unless you have a really excellent reason to and even then think about it really hard and decide not to.

And learn how to support basic keyboard navigation, damn it. It's just about marking up your html properly, no scripting required.

I think all of these opinions are popular on the user side.

Having ambiguous toggle labels should cause you to lose your job

Don't have a window named something like "Disable Features" and then the options be a toggle for "Cookies" or "Carry weight"

Does turning the toggle ON turn the feature OFF? Or do I need to turn the toggle to OFF to turn the feature OFF? Even worse when some are already in the off position.

I have a right to a page with all configurable options. A simplified interface is great but I shouldn't need to hunt for ages in a terminal or read source to find a config option.

Brimg back double-clicking on the top left corner of a program to close it. Actually, bring back the top bar and the file menu while you're at it. And for software that opens tabs, allow the user to position the tabs bar on the bottom or side of the screen.

• If it can be done without a touch screen DO NOT use a touch screen. And if you use physical buttons, they should have tactile feedback
• Toggles are just more ambiguous over-designed checkboxes

UI that isn't customizable is shit. I don't mean it needs to be Myspace level, but enough to make it comfortable to use.

Someone else said they hate infinite scroll. I love infinite scroll. Implement both.

I was interested in an open source fitness tracking app that didn't use a measurement system I'm familiar with. The dev basically said "fuck off" when someone asked about implementing it. Well, the dev has less exposure and their app has less users as a result.

I hate vertical tabs!
