There isn't really much in the OS yet, but the my goal was for people to make applications within a sprite, in which you can just copy the "TaskA" sprite and edit it as you please with the notes. Also Vicessor A1.3.0 is pretty much finished, its just that im not sure if i think its finished or not, i will probably release it within the next hour or so.
