Would be very helpful if we could organize tags into groups and expand/minimize groups in the dropdown box with a little plus or minus button- we have a lot (way too many) tags and it would be great to organize them into groups like 'location' 'school' 'career fair' 'verified' 'unverified' ETC so we don't have to scroll through all fifteen thousand tags to try and find the one I'm looking for but may not know the exact tag to just find it by typing

In that same vein the ability to mark certain tags as favorites when viewing tags on someone's profile so we can just have frequently used tags at the top of the list, under the existing tags on the profile would also be a big time saver

also would be great if you could restore the ability to just hit enter to add a tag rather than having to use the mouse to click the check box on a tag when viewing someone's profile

also, I am once again asking for the ability to use all boolean operators at once
