Currently, two fields can be filled to document what kind of change has been done to a page:

• Comment
• Minor change?

In my opinion, either a page edit is substantial and then the change should be documented in the "Comment" field (to avoid having to use diff to find out what was changed), or it is a minor change, which should be marked as such.

Right now, the default is an empty comment and an unselected "minor change" checkbox. This has the effect that in most cases users mark page edits as major without comment, which is exactly what should be avoided.

Implementing this would also have the effect of making people decide explicitely for each change if it is minor or not, which should improve the correctness of it.
