Where can I find a list of applications and other components of the operating system? (E.g., is the desktop environment KDE or GNOME? Where are the names of the applications menu, toolbar at the bottom of the screen, etc.?
It would help to have some sort of breakdown of all system components used, so it's easier to know if an app will work, like "made for KDE / Gnome" and what dependencies will be needed, etc.
