The form to add a new course category is ridiculously large and in the way

On the page to edit courses, there is a massive new form to add a new category.

It used to be very small because it didn't have a description, but now it makes that page unusable.

Can you create small separate script to do that job, something like course/editcategory.php and link to if from the bottom of the course editing page with a single button that says "Add a sub-category" (that string already exists).

At the same time, add a new little "hand" edit icon next to the description when it is shown in editing mode ... this should go to the same form so that people can EDIT the category description again at a later date (currently this is not possible!)

Thanks.
