I seem to need alot of space to keep my inventory sorted with multiple armour sets, and all the items used for all the classes (musky orbs, bard cresendos, etc). And in my situation I keep about 1.5 tabs free for other loot drops. From lvl chest to grinding. I think a few in the community would love to be able to have a 6th tab.
As a wise one once said, “space the final frontier”, so give us more space please
