Fantastic App… but

I love this application, it does just what I want and has the flexibility to use it however you might want to (i.e. creating a smart list for "Errands" that uses tags to filter is basically the same as Contexts in omnifocus). It has a myriad of keyboard shortcuts (which I love). The one thing that would be a little nicer would be the ability to add endless subtasks, rather than only one layer.
The main problem I have had has been almost constant crashing. There seems to be a variety of reasons for the crash (by crashes I mean freezes up and I have to force quit the app from the dock). Right now I tried to change my sync method and everytime I open "preferences" it freezes, leaving me without sync, or the ability to change any settings
If it wasnt crashing like it is I would give it five stars…
