 Potlatch 2: main outstanding issues
 -----------------------------------
 
-== Code tidying ==
-
-* A fair amount of the mouse-handling in each ControllerState is shared with others -
-  and some probably should be (e.g. unhovering). Can we refactor?

 == Core geometry ==
 
 * Undo/redo: split
-* Remove node from this way only
-* Backspace
-* Not messing up relations when splitting ways
+* Remove node from this way only (will require SelectedWayNode to become aware of currently selected index)
+* Bit more work required on relations when splitting ways
 
 
 == Vector background layers ==
 
 * TagTransform (cf http://wiki.openstreetmap.org/wiki/Osmosis/TagTransform)
-* Simplify (e.g. GPX files)
 * Import from OSM (is this worth sharing with the XML API stuff?)
