Tilda is a drop-down terminal for linux. Press the assigned hotkey and the terminal will dropdown and gains focus, press it once again and it’ll dropout. And even better, the terminal isn’t closed, just hidden.

This is great for development. I write some code, press Ctrl+S to save, Alt+Q for the terminal and make. If there is a bug I can Alt+Q and return to my code, and if I didn’t look closely enough I can press Alt+Q again to see the output again in the terminal.
