I am looking for a distro with a customisable UI. I want the ability to change everything in the UI: like changing the window borders style, animated interface, creating transition animations. Something that can allow me to create UI from my favourite video games. I am even willing to learn a language if needed. Just don’t suggest arch because I’m only interested in visuals. I don’t want to spend time creating and troubleshooting other aspects of os. Also, if above requirements can be achieved with changing the desktop environment, please suggest that too. I am somewhat familiar with Linux as I used it a few years ago for some time. Back then, the games’ support was lacking, so I switched back. But now with steam os and proton’s contribution, games shouldn’t be a hassle to run.
Linux is super configurable! You’ll just need to try out a bunch of different window managers, taskbars, etc to see which one you like best, but maybe look for some videos to preview a couple first.
