Enhancement request: Enter purchase amount

I find the bar to set the amount of goods you want to purchase a bit iffy. It inevetably leads to trying to fine adjust the mounts/numbers and ending up failing. Would it not be easier to enter the amount of money you would like to purchase for instead? (There is a posibility to enter the number of goods but what you really want to do is enter the amount of money you want to spend)


Yes yes yes please please we need this.
