[SOLVED]Discard/use item window when item is clicked

i would like to request a little window that pops up when i click on an item in the item menu,
that shows the possibility to discard or use that item.
should be simple no?

Modern Algebra's "Limited Inventory" should do that for you. You don't have to limit anything, but I believe it still has the "discard/use" option to it.
