An inputbox for an optional summary of the current edit (like mediawiki). This would then be used as the commit message, in place of "Updated foo.md".
I'd like to be able to add text to the git commit message when I save a page edit.
For instance - gitlab examines the commit message and if I mention a specific issue, it gets linked into the rest of the project.
Another idea. A checkbox to note that the current change is a minor edit (like spelling fixes) which could simply add the prefix minor to the commit message:
Minor: Updated foo.md
Minor: Fixed spelling and line break
