Drop down with global shortcut (I use control + ‘)

For me it is its integration with tmux, and therefore being able to use the command line in a remote computer as if you were using it locally.

I just use tramp for this.

I use profile triggers to change the color scheme of the shell when I SSH to a production server. The color I chose is different from my regular scheme so that it reminds me I am in production and things can break if I'm not careful.
