The idea is, once the Map layer is ready, we could have a button like "Compile Map Layer" which does the following: Generate a PNG with all the current objects present in the Map layer. Insert the generated PNG in the map layer. Hides all the other objects from the Map layer (hide them instead of destroying, so we'd be able to 'decompile' to fix any issue we find and 're-compile' after fixing any issues). Locks the layer until the GM de-compile the layer, which does the opposite of compiling. I think that would be a huge performance improvement, especially for those who draw their maps on roll20, and those who draw really big maps.
