I'm still on i3 as it's been convenient, but this:

this has all become very specialized over the past decade

resonates. I keep incrementally adding personal tweaks and hotkeys to my setup, and I have all my dotfiles in a repo so it's persistent across installations.

One example was I made my headphone button pause/play videos with i3's config:

bindsym XF86AudioPlay exec playerctl play-pause

But then I adopted a script to toggle mic mute on work Zoom meetings, so I combined it with the above - if I'm in a meeting it toggles mute, otherwise it play-pauses any current video. The script, for now:

#!/bin/bash
#
# Handler script for hitting mute on the headphone.
#

CURRENT_WINDOW=$(xdotool getwindowfocus)

# convoluted command to find the intersection of two searches
ZOOM_WINDOW=$(comm -12 \
  <(xdotool search --name  'Meeting' | sort) \
  <(xdotool search --class 'zoom'    | sort))

if [[ -n "$ZOOM_WINDOW" ]]; then
    # if zoom is active, toggle mic mute
    xdotool windowactivate --sync ${ZOOM_WINDOW}
    xdotool key --clearmodifiers "alt+a"
    xdotool windowactivate --sync ${CURRENT_WINDOW}
else
    # otherwise do play/pause
    playerctl play-pause # will fail if no player found
fi

and of course I altered the i3 config to launch that script rather than playerctl directly.

[EDIT: Updated script as Zoom updated its window identities]

Another i3 user here. I slowly transitioned from KDE when switching keyboard layout stopped working as well as some other DE related things.

Ended up writing custom script for switching. Currently implemented with rofi in Perl, bc I like the syntax.

I still like having a bit nice gui, so i have wallpapers, some icons, etc. But I fell in love with terminal ~~along with neovim : )~~ , soo kinda looking for that middle ground between look, performance and functionality.

Haven't finished tweaking all the configs to my liking, but after that vanilla Arch is the direction I plan to go, since many things in my current install that I have as well as haven't customized work a bit questionably or exist for no reason.
