Swap tokens in syntethic asset trading should have form validation to ensure send amount is less than or equal to their balance

If I go to https://flow.laminar.one/swap and enter a send value that's greater than my account balance of that token and sign the transaction it correctly gives error Swap error tokens.BalanceTooLow.

But I think it should show their current balance of that token near the send amount input field and perhaps have MAX 25% 50% 75% buttons for quick selection, and have form validation that alerts the user if they enter a value that exceeds their account balance of that token
