I've been using this a couple of weeks. There are a few things that annoy the heck out of me, but when I tried to revert back to Bagnon I found I'd rather be annoyed with AdiBags than use Bagnon. This is the best idea for inventory control by far. I'm just getting comfortable with adjusting filters, and I'll be trying out the PT3 filter shortly.
I really, really, really want to see my alt/bank bags. Tooltip-based alt/bank information is way too limited. I may have a greater essence in my bag and the tooltip will tell me if there are more in the bank but it doesn't tell me if there are lesser essences, and it tells me absolutely nothing if I don't have the item in my bag. Guild bank isn't as important to me, personally, and I can see how it would be difficult to decide where to put an item a player dropped into the guild bank. But would it be possible to provide a read-only display when the player is not at the bank?
The tendency to drastically rearrange the bag frame when moving items is also annoying. When moving items into the bags, I can see why the layout needs to be adjusted. It's just a bit disconcerting when I have to stop and look for the section that just moved from the top of the frame to the bottom, or readjust frame positions because the bank frame just laid itself over everything else. (Given this behavior, is there anyone who locks their frames in place?) But when moving items out of the bags, sometimes the layout of the section changes and sometimes it doesn't. I believe that most of the complaints I read would be addressed if the layout did not change when moving an item out of the bags.
Edit: Installed the PT3 filter, but it seems I have to already know the names of the PT3 categories and I can't find a reference. Could someone please direct me? Thanks.
