I'm mostly kinda annoyed at the fact that there is a swarm of items at times with 1/5 uses on it (especially in the EHSP section) mixed in with the good 5/5 uses ones.
I feel there should be a separate section for "used" shrine powders because off the bat when listing my own it shows me the lowest priced ones, but it doesn't tell you how many uses are left on it thus causing 5/5 shrine powders to be listed at the same price as one with 1/5.
I really prefer to skip the hassle of having to double check everything while listing and/or buying items with charges.
