Yes, please. Shortcut to bring up little dialog to enter bug number, or even enabling the Search to search the Bug Number field would be awesome. So annoying to have to open full bug list and scroll to find a specific number if I know it but don't have it open.

Yes, please...I've actually never used a bug tracking tool that didn't allow you save queries (or "filters" in your terminology). It is absolutely a Pri 1 feature!!!
