This is my editor of choice. Great work, MainMemory! Could'nt ask for a better editor. I do have a couple of suggestions though: 1:In the chunk editor, would you be able to possibly add ctrl+click block functionality to group select tiles and change their properties at once? 2:Also, in addition to Paste before and Paste after, how about a Paste - replace function? The Paste insert command is quite useless in the Chunk editor. Please do keep this project going, it's the best level editor by miles.
