TaskPaper Show Project List

TaskPaper is my favorite app (tie with CoverSutra).
One thing that itches me though is the way it displays Project List, in a non-native panel where I'm always afraid of deleting something and losing precious data. Given that the Project List behaves exactly as a good ol' source panel (think Finder or iTunes), why not display it as such? Here's a comparison with the original: http://cl.ly/1uMi
