Please find below some enhancement that I personnaly would find really usefull on the content class edit UI :

• add an edit button at the top of the screen while viewing a content class
• by default do not show attributes property but only name and type and add a button to expand and see full properties(currently with a lot of attributes it is difficult to identify the attribute you're looking for).
• the above enhancement would allow a more compact view of attributes and then allow an easy implementation of drag'n drop for sorting attributes.

What do you think ?
