OP, a term you may find useful is ricing. This is the sub-community of Linux users who focus on customizing their desktops. You can look at the unixporn subreddit to see examples of how much a DE can be customized. Ex: This is KDE Plasma This is also KDE Plasma This is also a, very customized, KDE Plasma (video)www.reddit.com/r/…/kde_my_2nd_ever_linux_rice/ Another is dotfiles or dots, ricers will sometimes make their .config files available for other users. (Be careful here, this can include hidden malicious scripts and such uglies. Use your best judgement).
