I think this will be the trend. Release a minor release every two weeks! Anyhow, here's v0.2.3, and the changelog:
* Fixed: circles to be more accurate with grid
* Fixed: layer deletion code to delete properly
* Fixed: Layers list out properly when working with several image windows
* Fixed: Adding a layer in an animation doesn't mess up the project
* NEW: Added author field to project info
* NEW: Layers and animation controls in separate windows
* NEW: Load in images through datatypes
So get productive and start animating :-)
