Usability issue

When writing commit messages I'm missing the following information (at 1 glance):

• How much more can I write in the current line?
  This is kind of available by the "x characters left message" but I find it easier to recognize a line which is "coming closer" than a decreasing written number.

• Do all lines of a multi line commit meet the desired max line length?
  I can already move the cursor through all lines and wait for the "validator" to turn orange or stay green but I find that very laborious mainly for 2 reasons:

  • There's no way to tell at one glance if the whole message is valid.
  • When moving the cursor 1 line up or down, I always have to wait for the "validator update" and if it doesn't change I'm always left with the feeling of "did it maybe not update correctly"?

Solution/Request

• Monospaced font in the commit message textbox (by now possible with setting scm.inputFontFamily)
• The textbox should not "auto-wrap" but show a horizontal scrollbar if needed
• 2 rulers at the values from settings Input Validation Length & Input Validation Subject Length

I see that this is at least related to #2718 but created a dedicated request since I'm not looking for any "auto correction" but only a better visual guidance.
