I'm aware of the "grouping" functions which is similar to merging except you can undo it - so in ways it's even better. However, since having many objects can slow things down what would be amazing is if you could construct maps in roll20 using many many many many objects, and then merge everything visible (that you don't need to be able to move later on) into one map object to have less things on the map that need computing. It would be great because photoshop doesn't have a grid to snap objects to so I have to move everything around carefully and that takes a while... In the moment the only option I see is building map layers and then taking a screen shot, but that might mess with resolution and I have to be careful with the zoom level, etc. Anyone else think this is worthwhile? Is this at all doable? Julian
