What about including a "special bag" for every hero in their inventory at the start of a new game.
This special bag is on it's own your "crafting" window wherein you can/have :
1) different tabs (OR: a sorting menu!) : like Arne wrote is a possibility ... a tab for alchemy, tailoring, blacksmithing or weapon-making (in general), scholar/scribe, ALL ITEMS
2) you can also repair all your gear in this special bag window (if you've a repair hammer).
3) you can identify all gear also (if you've an identify glass).
4) a "search" function ?
5) ... maybe more ideas or possibilities ... ?
OR maybe the window wherein you've your Journal/Secrets/Recipes/etc ... also a tab for Crafting ?
Just some tips
You mean like an extra backpack which sits in your inventory and can be moved around like the other backpacks?
Assuming that's what you mean, that's the kind of solution that I'd expect from a modder, but I think it's a little too clunky for an official fix.
The Repairing and Identifying parts could be fixed by Larian by adding in a couple of buttons in the inventory screen, one for repairing and one for identifying. They only light up if you have Blacksmithing AND a Repair Hammer, and Loremaster AND an Identify Glass. That way you just click the button to toggle on the icon (changing its appearance) and can click the hammer/glass icon over all items needing repair or identifying, and you hit escape or the button when you're done to get out of Repair/Identify mode.
I don't think there should be a new bag for crafting, but it could get its own new UI, also accessed through a button on the inventory screen.
I'm not sure how a "search" function would work, that sounds complicated and probably a bit unnecessary.
I don't see the need for adding a new bag which has its own tabs, when there are already so many existing tabs. It would just be confusing.
I do think adding a new option to the right-click menu "Tag as Junk" would be a good idea, it would tag the items as junk for sale, and add a little $/gold pile icon over top of them in the inventory, it would add a new Junk tag to the sort-by menu, and of course when bartering, you would have a new "Junk" tab on the barter screen letting you see exactly what you have tagged as Junk for faster sale.
