On the Sort Form of Manage Entries, you can select Gallery and then Category.
I think it would be great if once selected the Gallery, the Category list displays only the categories in the gallery selected, instead of all of them. Why? Well, I have hundreds of categories separated into various galleries, and when I need to select a Category the list is massive.
Another feature I’d like to see is the Category list to be alphabetical, since it would be much easier to find stuff.
