Add tag/group selection into New Individual/Org/Household page

I just held a training session with one of my CiviCRM clients, and it became apparent that the workflow for adding a new contact is too clunky. I assume that adding custom data groups into the main "add individual" screen has already been feature requested (maybe I did it). But here's another one: add check/select boxes for Groups and Tags to the main add contact screen. I know this makes the page longer, but it is too grating to have to click Save, then click the Tags tab, then click Edit, then check a box, and then Click Save.

The +/- show/hide functionality is really sweet, I'd say use it by squeezing lots of stuff in one page.
