Wallet display in shop menu

In the main menu I can display my wallet, see all my resources and can check, what I need. In the kingdom bazaar I can do that too, but in the shop menu I can’t. I can’t display my wallet from here, I have to go back to the main menu. So it would be nice to display my wallet from the shop menu too.

Alternatively, it could be displayed, how much of a resource I have, when I click on the item. It doesn’t make much sense in spending gold, gems or even crowns for items, which I have in plenty.
