If you use Sublime text for coding or taking notes, then turning on autosave might be super useful. This ensures that my files get saved and synced to dropbox without me having to do anything, so I can always pick up where I left off on a different machine.

Seed Ship Jan 22nd

If you liked paperclips, a dark room, etc but you only want to spend 10-15m playing then, Seedship is definitely worth checking out. More games like this please!
