- Simplied the task icon - Created common treeview for States, used for state selection and outliner view - Added common functions to describe state links and transitions - Made custom expander arrow the main tree view - Move the task lits on separate row on the main tree view - Added enter condition list for on main tree view - Clicking on tasks or enter conditions highlight them in the details panel - Added state outliner which displays the state list compactly - Added feedback for the drag and drop, and moved the code to separate file #rb Yoan.StAmant [CL 35239895 by mikko mononen in ue5-main branch]
