Cache flush rules

First off - fantastic plugin. Thanks for making this available!

Secondly, it seems like batcache employs only very simple cache clearing functionality out of the box. What would you recommend in order to implement more granular cache flushing like one might find in W3TC? Would you recommend just creating our own simple admin UI to flush the full cache or individual pages, or is there a tool already in place to do these types of things? Thanks!
