Emoticons Categories - Add option to toggle open/closed to aid reordering

[The Old Man]

Hi,

The long awaited improved emoticon management is brilliant, love the drag and drop categories, but it can be very cumbersome to reorder categories in AdminCP if you have categories containing a lot of emoticons (several rows that require lots of scrolling).

Please can you add a simple + or - option to toggle categories closed/open, so you can drag and drop closed categories much easier on the screen page because they would be condensed.

Many thanks!
