bbebop, if you move stuff off to the archive once a month or so, you'll be fine.

I ran into this problem primarily because I have many actions that repeat once a day, and because I was using OmniFocus for six months before you guys had access to it.

Realistically, the phone can handle a thousand or so actions just fine. Minimize your completed actions on it, and you'll have plenty of room for forward-looking actions.
