Linux is my primary and only OS right now, I'm using Linux Mint 18 MATE. I've never used a window manager like i3, but the screen real estate and mouse-free functionality that they offer is making me want to use one for coding.
My question is - how does a window manager fit in with the greater every-day use of my computer? Could installing it break my system? Will it toy around and change some files "irreversibly" (i.e. it'll be difficult to get my original setup prior to installing the window manager, without restoring a backup)? Is it as easy as a regular program to uninstall (i.e.
sudo apt-get purge <window manager name>)? Can I just switch to it when coding and switch back to the original MATE desktop when I'm not?
