I'm trying to find a light bag addon, where you can set up some Categories like in Arkinventory, but I think Arkinventory uses to much resources.
Any suggestions?
Setting up any categories at all, like ArkInv, creating dynamic displays customizable to your every whim, is inherently resource intensive. Either accept the cost of having the best bag mod out there, or go with one that isn't as customizable. I've really enjoyed Combuctor, and have watched its development, and it has a lot to recommend itself.
