I get that there are different Distros and that having options is great, but it's a double edged sword. It also means that things get more complicated and some get more support than others.

If I commit to Linux then my whole house will switch to that Distro because I don't have time to figure and support >4 PCs with similar but different OSs.

Autocad - for work

Photoshop - for work

Getting more software companies to support.

Make the terminal easier to use. I don't use it often but when I do I waste an average of 15min just trying to find a guide or wiki. A help file or built in guide would be nice

Everyone that uses Linux, expects you to be a Linux expert

Steam is great but a native GOG app would be nice. Instead of Herolauncher

Anti cheat support from games

Hardware support. Just finding drivers for peripherals is sometimes more trouble than it's worth

Generally make it more inviting to new users

More support for WINE and Proton
