Numpad UI when dipping gold

On tablet (iOS or android), dipping godl means you have to use + and - buttons to set the amount. These increment very quickly, but in the latest iOS beta I noticed it's a bit worse than before. The frame rate is the same, but the UI seems to update less frequently (so the gold amount increments by bigger amounts). I'd love just a numeric keypad to appear when you dip gold, so you can easily enter the exact amount you want.
