I have been using the "Save & Continue" button quite a bit lately - and I've noticed that any comments you type into the text area labelled "Short description of changes" are left unchanged after clicking the button.
Whilst in effect it will simply save me the hassle of deleting it manually and therefore isn't a very important wish, I'd like to suggest that this text be cleared after the page is saved. Then I can type the next description in immediately, instead of deleting the existing text first.
