Add additional filters to Ideas content page in Control

It would be very helpful to be able to filter this Ideas page in Control by Author, Publish Date, and Last Activity. I know we can sort by the dates, but for example, if we are just trying to look at the ideas published in Q2, we have to go through the entire list and just select those ideas. Similarly with the Last Activity date, I know we have the ability currently to filter by Last Status Change, but sometimes we need more detail - when was the last response or comment on an idea, not a Status Change.
