Thanks Mike!
Ctrl+T... very nice! My mouse is booking it's holidays after seeing that in action.
I need to experiment with different multi-monitor layouts, see how to make best use of it with GMS2.
I guess even just having docs open in an external browser could help there, if the browser is side-by-side or on another display.
I tend to agree that default origin = centre would probably result in fewer people needing to change it.
Although it's highly situational, and at least it *is* configurable, so no worries.
