5 months ago @danirabbit I think this is worth a look now - I have tested as best I can using dummy widgets faking three monitors. I assume that the user drags the displays into an approximately legal position at least - in which the displays should snap together. Otherwise the displays remain where the use placed then and the "Apply" button is insensitive,
Avoids flickering while dragging, deals with three monitors better, Apply button insensitive unless displays legally connected.
