The commit detail windows is too small, and it can't adjust size! Could you please let it can be enlarged after I click the bottom of the windows of commit message and drag it down to enlarge the commit message window?

And if the message is too much, I can't see whole message when I hover on the commit. Could you add a slider that can show the more message below?
