though the map editor is good there a few improvements id like to see come in
since u can group things and name it as a group and then hide said objects in theory i should be able to reuse that space (that the group is hidden) to place blocks/tiles etc over blocks in that area since its free of anything since the build of it is hidden this would be useful for the follow
A. building upgrades as in change the shape or style of a building be it the roof or shape of a building (since current even if a group is hidden it changes the block to whatever u've place in its place regardless of if the group that is in that place is hidden
B it would give the ability for games to have more then one group to be in the same area and less strain on the engine in terms of getting the engine to manually replacing tiles and via code witch when i do it at lest causes long loading times and lag on the engine in and out of gameplay
C it be so much easier for a beginner to show and hide groups to make a system like this if they was able to have 2-6 different builds in the same area and in code they can show and hide the right group of objects
