I know we only have 5 different blocks, but I’m assuming that slin is going to add more. I propose an editor overhaul.
How this would work is instead of having all the blocks laid out; the blocks would be in sections. So you would have stone, ice, grapple, etc. You would also have a drop-down menu of all the different types of blocks(cube,sphere,etc). This way if more blocks get added, they would be easily accessible.
If you want to go above and beyond, you can make it possible to select the block that shows on the front, and be able to take that instead of having to go into the drop-down menu.
Edit 1: All the miscellaneous blocks(start,finish,sign,grav) could either be in a different section labeled “Misc” or could just exist in the menu.
