For now, I'm trying the method suggested by whpalmer4 in this thread:

A parallel project containing two items, the first being an sequential action group that repeats as required, the second a reminder to mark the action group as complete. This still means going to project view but at least the completed projects dont pile up.
I'll need to test it for a while before I can judge if it fills my needs. The problem is that the 15 day test period doesn't allow for many repeating projects.
