I've made lots of progress on https://Mammudeck.com. But I can't describe it here in one post, since the maximum post size is so pitifully low compared to typical Pleroma sites. So I'll just post some screenshots.
The attached image is what my https://Mammudeck.com page looks like for this server.
Mammudeck is still alpha software. It works well enough to make this toot, but there's still a lot to do: https://github.com/billstclair/mammudeck/blob/master/TODO.md
Mammudeck is a web client for the Mastodon REST API. It's basically TweetDeck for Mastodon (and Pleroma).
This is a brand new server run by the main developers of the project as a spin-off of mastodon.social It is not focused on any particular niche interest - everyone is welcome as long as you follow our code of conduct!
