One way I was able to make it a little easier to move is to assign the following code for LineSymbol of sketch style of the geometry:
new SimpleFillSymbol(SimpleFillSymbolStyle.Null, Colors.White, new SimpleLineSymbol(SimpleLineSymbolStyle.Dash, Colors.Yellow, 2.0));
This way you don't have to click on the outline but click on any part of the geometry for highlighting and moving.
However, I feel that once you are in edit mode or creation mode, you should be able to move (drag) the geometry without the extra click to highlight it.
Thanks!
