I have a few requests for the map editor.

First of all, it would be *epic* if our selections could be more complex than just squares: Shift-drag to add and Ctrl-drag to remove would be epic.

Second of all, a check-box to only show variables that are modified on the variable viewer would also be great.

And finally, it would be nice to hover over an instance in the instance panel to show a list of all modified variables.
