Simple, syncs with iPhone, and shows progress effortlessly

I love that you can see your progress on each task for the past week at a glance! And clicking on the habit shows the last month(s).

The OS X application currently has two bugs:
1) it will not remember where you’ve set the divider between the progress and titles. I have normal-length titles, but they get truncated in the default size.
2) opening and closing more than once from the menu bar causes a crash.

I would like to have the ability to group the habits, instead of having to see all of them at once. - Same thing on the iPhone. Maybe a tabbed interface?
