Tapbots, on their upcoming Mastodon app:

Ivory is currently in Early Access, which means there are features missing and we are actively building them while you get to use the app.

If you don’t like using software with missing features, we recommend you wait until we are out of Early Access and evaluate then. But you’ll be missing out on a lot of the fun!

They’ve also published a roadmap of what they’re working on or are planning to work.
