@Moblyn Thanks for the detailed input on this.
Animation is the most requested feature and something I hope to get implemented further down the line, maybe version 1.5.
I have looked into several different ways I could implement it, and will hopefully do some testing soon and get a plan in place for development.
Reference having a pixel editor built into the software, its very unlikely this will happen. I have always seen this software being used in addition to other great pixel editors such as Aseprite and Pyxel Edit. However, procedurally generating animated sprites is very much on the radar for future versions.
Watch this space!
