Logbook for 37Signals’ Backpack.
Transmissions’ Logbook is an application with a very specific purpose: quickly and unobtrusively updating a Backpack journal with your status and completed tasks. It sits in the menu bar and can be invoked with a keyboard shortcut.
It’s a beautiful little application with an equally beautiful web site. If you use Backpack, give it a look.
