Some of the reasons I really like KDE:
* I have keyboard shortcuts for switching desktops; I feel much more productive with 9 easily accessible virtual desktops. I use the "windows" key, sometimes called "meta": meta-Q, meta-W, meta-E, meta-A, etc.
* I've added rules for automatically changing the window title bar colors to make it easier to distinguish between very similar-looking windows. My Sublime Text windows in particular have a different bar color for each project. Sometimes I have as many as 4 projects open at once.
* I can lay out and enhance my screen any way I like. KDE doesn't quibble and even encourages it.
