How about "Sort by Type". I know you can click on tabs to get JUST each type, but sometimes you want to look through everything but have it organised in a meaningful way. So far you can say "Well, this is by cost so I can see what to sell", or "this is by weight so I can see what I need to get rid of 'cause I'm carrying two tonnes of crap" but it would be nice to just sort everything down to type to get an overview without going through each type individually.
And yes, the immediate tooltips are annoying. There should be a tooltip delay option. Also, perhaps a "no tooltips but you can press CTRL and get a tooltip instantly" setting.
