Same, I switched over yesterday and I found it actually does all the things I was hoping for!
Reducing keyboard size, removing suggestions bar, adjusting timing on holding for symbols or numbers, emoji key, theming, and swipe typing can be enabled (its just a file that they cannot or have chosen not to install with the app, as the rest is open source as far as I understood).
You know, I’m really curious about xmpp, kinda wanna check it out, but then every time I am reminded that it exists it comes with a new and different chain of dependencies? other apps? whatever the other things are anyways that people list with it. And then I don’t bother researching because suddenly it seems like the more complicated option. Not intending to insult, just lamenting.
