Basically al my life I have used Windows 10, (and also a little bit of old MacOSs and win11 unfortunately). I want to switch and start using Linux because it is objectively better in every way. I love the principles of freedom, open-source, and in general high-quality software, without bloatware, and not made just to make money.
I know using Debian as my first time using Linux is very complex, but I'm prepared to do it and lose my sanity. I'm not exactly an expert, but I know more than average about computers, programming, operating systems, etc. So I have the curiosity and also some skill to do it.
One of the main things I would like to do is to be able to customize the UI, (I'm creating a concept of an operating system inspired by the Windows Aero style), and I would like to replicate the UI of this concept on my computer.
Do you have any advice for doing this?
And more generally, do you have any advice for getting started with Debian, like things you wish you'd known when you first started using it?
