Toots look quite nice as well, however there aren't multiple panes for federated, local, following, etc. like there are for Mastodon. I have seen that Pleroma is fully compatible with any Mastodon client and, according to what I read, that even includes the Mastodon WebUI which is a big plus; I love versatility and options.
1. User settings: 2FA, Bio, PFP, etc import/export, etc.
2. General Settings: Background, theme, notification filtering, timeline view, etc.
3. User search
