Thanks for the replies!
I am using kRO, I just put some translated .lua files.
Anyway, even regular items, mostly with "5" item type aka. Armor fall under other categories...
For swapping the window names, yes it would work but the problem is that when I click the Shield icon, I want to open the armor, not the weapons... Same for the Sword icon...
Anyway, it's just mostly aesthetic so I don't really care much if it stays that way, just wouldn't hurt to fix it somehow...
