Rod Schmidt has released an update to PackRat, quite possibly the only offline Backpack client, that brings a major new and much-requested feature: the ability to add, edit and delete reminders. Now I've mentioned PackRat once or twice before here at TUAW, and this rockin' new feature almost completely rounds out what I think is the killer offline and syncing app for working with Backpack. About the only thing missing now is calendar editing, and in a blog post announcing this latest version (0.94 to be exact), Rod and gang offer a glimpse of PackRat's future, with a promise to take your Backpack data into a realm of Mac OS X integration that 37Signals could never accomplish (due to their service being 100% web-based). Coming down the pipeline are features like Spotlight and AppleScript support, Address Book and iCal integration, iPod syncing, and "whatever else makes sense." Sounds like this handy little app is in for quite a ride.
PackRat has a fully-functioning, non-expiring demo that allows you to edit up 4 pages of your Backpack info (the free default Backpack account offers 5 pages), while a license costs a mere $24.95 which unlocks full editing of all pages in any of the paid accounts that offer more pages.
