/* Developer mode (Middle click) -
developer pane ONLY shown during developer mode.
make main pane widgets dragable and resizable.
allow add / del widget.
allow editing widget "extra skin commands"[1].
allow add / edit / del modules, panes, commands, parameters.
Do some general "edit Thing" stuff.

[1] widget extra skin commands are commands in the
skang file that relate to a widget - action, look,
method calls, etc.  When writing the new skang file,
add them after the widget creation command.
*/

/* User mode (Right click, or from Right click popup) -
Like developer mode, but only
widget add / del / move / resize / edit look allowed.
No developer pane needed.
Allow "Save skin" and "Revert skin".
Allow "Add module", after modules can add to the classpath.

MAYBE -
Right click and drag widget.
Right click and drag widget border (three pixels around widget).
Right click popup - "Add widget", "Copy widget", "Delete widget",
	"Edit look", "Add module", "Revert to old skin", "Save skin".
New SkangAWT command "menu name,text,action" adds to popup menu.
