Nice. These look pretty good. Much better than the default chat input. Tempted to use one of these in chat.py. But probably better to keep it as the default for simplicity.

Maybe one suggestion I have it to wrap the examples in a @me.component to show how these could be reusable. But I think that will be more useful once you add the copy code stuff in #579 and #580, so I think fine for now.
