Allow us to combine bags to open in different frames.
example: we have 3 normal bags and 2 herb bags, we combine the 3 normal bags into one and the 2 herb bags into one, them when you open your bags you will see 2 different frames, one with your 3 normal bags and another with the 2 herb bags.

Why not use Combuctor, which is designed with that purpose in mind (separate normal from herb/mining etc bags)?

I would prefer to see it in bagnon instead.

I would love to see this same feature aswell. Baudbag offer something similar (you can seperate bags from the main display) but you cant link the seperated bags together, so if you have 2-3 LW bags, all 3 bags are seperate from eachother aswell as main bag.
I much prefer using Bagnon so to have this feature with it would be great! :)
