Close the "Show Gear" screen after purchasing

Just a minor thing, really …

but the “gear (purchase) pop-up” sometimes won´t close automatically after spending your shards and having nothing left to buy (currently) … I feel like it does so some of the time though, does it not?

Anyway … I think that that menu should reliably close automatically once you can´t buy anything else. Closing it manually doesn´t take much time but during combat you shouldn´t have any unnecessary controls getting in your way.

What do you guys think?
