Checkboxes for "all FX" "all Instruments" "all hosts" "all dev tools" would be good, so you don't have to manually enable/disable all items in a group.

Being able to watching searches would also be very very nice... so I can get an email when there is a new Windows VST distortion effect for example. Maybe it would be wise that you get max. 1 email a day (a week?) though, with new items of all searches you are watching.

That's it for now, if I come up with more I'll post it here

I love all the search options. You can really fine tune it. I was wondering if it was difficult to add another option to the "Developer, Product, & Date Added?" How about some sort of "Price" sorting? For example, I was recently looking through the commercial guitar VSTis - but would have liked to have been able to stack it from lowest to highest list price.
