With the new system upgrade we need a ton of jewels to upgrade our itens so, its exhausting to select the item and the jewels 1 by 1, cause everytime you hit upgrade buttom, you have to select the item again.
You do it 10 times in a roll and man, feels bad. Now do it from 1 to 500 in one shot…
So, the idea of improvment here is that you could select the item and a bunch of jewels at once, doing for exemple upgrade from 1 to 15 in one shot, as long as you have the jewels.
EDIT: a fine way to solve it that i just thought is add a “lvl up to max” buttom. you select the item and hit this buttom and it will find all the jewels in your bag and upgrade it to max lvl possible.
