Version 1.5 of TMI Manager has just been released on the AppStore. I have completely rewritten the photo management feature, using Nimbus Photos as the foundation. I'm pretty proud of it, frankly. I added on a CoreData extension to the Data Source, and it works really well.

The nice thing about how Nimbus Photos works is that I'll be able to, with great ease, add different types of images and document types. I need to do some work on the website to be able to sync properly, but once that's done, it'll be a snap.
Thanks for doing the work on Nimbus that you've done, @jverkoey. I'm looking forward to integrating more of the library into my frameworks, and gradually replacing Three20.
