Editing categories

I added my private categories to the preset list. In the left panel the order is alphabetical in all browsing options. I planned to change the order by adding numbers to the names, or letters A-Z, because I didn't think of this before I added the categories. This way I want to move them to the beginning or end of my lists.

In the pref. database customize I couldn't edit the categories. If I have to open a new one and move the contents, and maybe move it back if I don't like it - then it's good that at last I know how to do bulk editing.
