They have repeatedly brought up that they're working on optimizing things on the back-end so that they can add more space...

They mentioned for example that they could backup stuff less often, but that would mean higher risk of losing items in case of a server crash.

Any change being done also needs to be really carefully done in order to not break our existing inventories.

There are plenty of things I'd like to see... A component inventory... A tackle box... A fish box... Things that don't need to be immediately available when opening the inventory. Things that is enough if it's synched with the server when you're trying to see what's there (like retainer inventory).
