I think it's best to keep any support inquiries for a mod over at UBBDev in its mod thread (as modifications aren't supported here).

To answer your questions though:
1. You know, I don't think there is yet
2. There is a cache with the script, it'll only add once the timer is up (and there are new entries in the feed); this is adjustable in the "Cache Refresh Time" area.
3. No.

I am a Web Development Contractor, I do not work for UBBCentral. I have provided free User to User Support since the beginning of these support forums.
