The last time we heard from Bitolithic about its all-in-one iPad productivity app ThinkBook was nearly 10 months ago, which was on the occasion of the app’s Retina iPad graphics update. Now, Bitolithic is finally back with another update to ThinkBook:

Hi all, it’s been a while since updates but this one is a big one. It took a while to re-jig ThinkBook’s innards to do what we wanted and from now on things will be happening faster.

The latest update to ThinkBook brings some minor improvements and bug fixes, along with a major new feature: attachments.

ThinkBook now supports attachments, i.e., multimedia files imported to the app. These include documents, photos, videos, and audio files added to ThinkBook notebooks and pages. And all of these are held in a new note type called Attachment note.

Note that attachments can be imported to ThinkBook via iTunes file sharing. Or more easily, they can be imported from other apps via iOS’ “Open In …” functionality.

In addition to attachments, ThinkBook has been updated with improved themes, including the new and colorful “Earth wind and fire” theme.

Featuring the same innovative slider found in Bitolithic’s popular comic book reader, Comic Zeal, the newly updated ThinkBook for iPad is available in the App Store for only $0.99.
