For people wanting to try i3/awesomeWM/anotherTilingWM: Learn all the keyboard shortcuts, not just the basic ones. Spend some time on perfecting the configuration for you. Make keybindings that make sense to you.

Tip: Once you realize that you can make everything tabbed/stacked, your workflow becomes really fluent.

Example:

Workspace 1:

    Stacked (left):
        VIM - ASM / C
        terminal
    Stacked (right):
       ddd
       firefox (stackoverflow ftw)
