As an option: Right now, we have a feature to select multiple currencies to display, but only one shows. I think there should be an option where, when you gain a currency, the currency indicator temporarily changes to show you the total of the acquired currency. This is usually how a lot of other games work: you get the thing, the game flashes your total on screen, then it leaves your UI after a few seconds.
As an aside, the font for the currency (not the currency window; the one on your UI) is really bad. Feels like some changes can be made. Mine is at 110% and still requires squinting to read.
