Lots of work has been done on this little beasty. Animation is now supported (runs in a separate thread) as well as a host of other new features.
Will let you know when I need testers. Yes, I've made lots of backups on my system and on the dev team's systems so I won't lose this one.
If anyone can think of a feature they would like to see in a tile editor, lemme know about it and I'll try to implement it if it's practical.
