How to Use Kivy on

I made the Kivy  Python cross-platform GUI framework work in a GFX REPL on . is a multi-language cloud IDE with good support for Python.

Copying all the text of other users’ tweets makes me uneasy, especially considering those users may not be aware of it. Therefore, I turned off listening to webmentions from Twitter and deleted the Twitter reactions had initially added as comments to my posts. The blog is
