[FEATURE] Show understandable errors
**Is your feature request related to a problem? Please describe.**
I'm working with Tron main net, and USDT (TRC-20). Pretty sure that this will apply to other cryptos as well.
Sometimes I need to do manual payouts.
Sometimes payouts "fail" - to know what went wrong, I need to go to the log, and see the error.
Would be really nice if the error would be shown right next to the payout, together with some alert appearing on the screen.
In some cases, when you specify the max fee amount and click `send`, there's no error in the logs, no errors on the screen, and the status doesn't change (also applies when there's not enough funds).
You are only supposed to guess that it didn't work.
Would be really good to add some error/warning information for those as well.
