The Freddy's Revenge Release

This versions updates the demo app. The previous demo was written quite a while ago and needed a refresh. It's not quite finished (there are plenty more widgets to cover), but it is still a bug improvement over the old one.

python -m textual

Give it a shot, we think it is pretty fun to play with.
