Would be nice to have a button/icon next to the selected token in the swap interface for refreshing balance(s). I find I use Keplr to IBC tokens into Osmosis (or claim OSMO rewards) often, and I have to refresh the screen every time to see the new balances reflected. Why reload the entire UI when a round-trip to fetch updated prices would make for much better UX? Simple little button atop the swap UI, a la the mockup screenshot here, would do it!
