Load More Items in Recent List Tab

Current the number of database loaded in the recent list tab is limited due to performance consideration.

It would be nice, instead of loading only 7 items, we could merely refresh the info of only 7 items, and only refresh the cache.

Sounds good. Or actually make the list more dynamic. We only load items that is visible. Also if we want to display more stuff, it is better to have a way to remove item from recent list so people can remove unused item from the list.
