Hey @ketamu, thanks! i'm glad you liked Laigter! Current version 1.7 has a lots of improvements compared to 1.4.
About the brush, is in current development, and for using it you should compile Laigter master branch, and the brush, or wait until 1.8 is out. If you want to compile it, first try to compile Laigter with the info in the readme in github. You can join Laigter's discord server to ask for guidance in case you can't make it. After that, you should compile the brush.
About the Sprite Animation preview, i'm not working at something like that at the moment. In the future perhaps i add support for spritesheets and let you cycle between sprites to produce some kind of animation preview, but idk if i will be able to do anything else on that field.
