Hi Sebastian, I'm glad that the Mac version is useful for you!

I'm just about ready to release a new version which has some various tune ups, like native file open/save dialogs and some other stuff to make it a bit smoother.

Once I've got a few more of that kind of stuff finished up I will then package up a v2.5 full (non-beta) release and that version will be available for v2 owners, so you won't have to wait until all the way until v3 is finished before having a full and non-expiring version available.
