Just a quick note that Logbook by Transmissions has been released today. It’s a client for the Backpack Journal from 37signals (part of Backpack), and lets you manage your tasks and status right from your Mac OS X menubar.
Instinctive Code (my OS X/iPhone development persona) is pleased to have been part of the development team for Logbook, providing custom UI work amongst other things.
If you’re a Backpack user, be sure to check it out - and keep an eye out for future releases from SignalApps to integrate with your favorite other 37signals web apps.
Clarification: please contact Transmissions themselves (support at transmissionapps.com) with any enquiries or comments regarding Logbook - I’m not actually part of the company. :)
