Drag/drop and Multiselect for fields etc in desktop library editing
In the desktop client library editing you can only select a single item and you can only move, copy, delete, or move to a page with either the toolbar buttons or a rightclick menu option !
This adds loads of time and frustration to editing or designing a library - the items should be able to be multiselected and moved by drag and drop and the rest of the functions (copy, delete, or move to a page) should act on all selected items. It is making the design stage a far more tedious job than it needs to be.
This is pretty much the only thing stopping me from parting with my cash !
