I do appreciate this feature. But there is one issue with it. Everything skips properly except the UI weekday/end. So when I skipped ahead, it was the Wednesday, but my UI would think its Friday. Then I would end up with 2 sunday events, cause of the calendar sunday and then the UI sunday. I had to skip 5 days several times more before it syncronized back to the appropriate weeday/end.
Also, I'd honestly flip the list from (skip 30, skip 10, skip 5, skip a day) around. So skip a day on top, then five, 10, 30. That way you don't accidently hit the top option and skip 30 days. =T
