Allow Symbol Instances to update during master symbol editing
When making patterns or complex design based on instanced symbols it's vital to see how the seams between repeated symbols update. It would be good to see all instances (in view) update as you're editing a "master", and for the alignment tools to take the other instances into account so you can make pieces align with each other across a grid. Today the instances will only update AFTER you're done editing and it makes for a lot of going back and forth.
