cannot amend message

[hugodu69]

Is your feature request related to a problem? Please describe.
being able to amend the message of a commit

Describe the solution you'd like
for example, clicking in the message panel on the lower right corner could open an editor to amend the message, or right clicking on the commit could allow this option too

Describe alternatives you've considered
for the moment, if i do in the app instead of command lines, i rebase-interactive to reword the message, but that's just a trick, and a little bit confusing if it's not for the last message

Additional context
context : i really like you app, tank you a lot :)
