There should be some notification in the fxwallet that the validator node has edited something (% fees, for example), notification like when we receive a WhatsApp message with a number or something.
Think that would be nice addition.
But for me, i hope (and expect) that validators will make it more personal by communicating fee changes through socials for example.
That they do a little bonding with their delegators.
A notification when validator is offline or jailed for example would be more desirable.
