I can't speak from personal experience but I would recommend this video.

And it's a channel aimed at gamers. Seeing Wendell serving as advisor gives me hope that they can get good results and i agree with the choice of distro

I'm going to assume you've used the terminal before. Since you're not afraid of some fiddling I recommend Fedora or CachyOS. The desktop and hardware work out of the box on newer hardware and Wayland has great support for multi monitor. Get flatpak. Stay away from Nvidia.
I don't do pirated games but since you're not updating the game you can use Bottles to install non Linux software or maybe Lutris.
I'm running arch (on AMD) and just installed Fedora on my partner's computer (with Nvidia RTX 4050) both using Heroic and Steam for games.
Just keep trying what works for you. Linux is improving more and more.

Fedora KDE would be my suggestion

Just remember to pay forward. Go to local music shows, buy merch from the bands you like

I think you're referring to the "file picker" window. i think qBittorrent is using Dolphin as the file picker and as everyone else commented already you can get the same behavior if you use the "Details" view. Go the settings on Dolphin and tick the Expandable option

Alternatively, you can add the Folder panel (F7) and have the same functionality while having a "Compact" or "Icons" for the files

Maybe there isn't a market for it. Probably most crackers don't bother with Linux versions and the Linux community always tends to support FOSS software.

I think you nailed the first paragraph.
My comment is just to remind that OP is already running an immutable distro on the Steam deck. Valve OS is an arch based immutable distro.
Bazzite was assembled, by some very cool people, to bring the same features of the Steam deck using the already tested atomic editions of fedora to a multitude of "PCs". Saves time on managing the "Linux" system and focuses on the gaming features, apps and drivers.

I've been following her for the past year, it's a pity she doesn't have a one time contribution scheme set up. I also can't support everyone but judging from the donations on KDE people do tend to give small amounts and it really helps. Gonna try to contact her and see if she can accept something like that

I thought it was about the true story of how the USA was built

NixOS is the sort answer. It's reproducible across hardware. But I've never tested it.

Energy wasted to create an AI image to have more energy wasted to have an AI remove it. I'd say this is a win for AI
