I’ve looked at a few on fdroid and they all seem like they aren’t being maintained anymore.
Edit: I’ve spent the past day trying most all of the suggested keyboards here and I think I’ve landed on either Unexpected Keyboard or AnySoftKeyboard. Thanks for all the suggestions. Thumbkey is quite the thing to get used to.
Unexpeted Keyboard is the one for me. Takes a bit to get used to but I wouldn’t want to use anything else anymore.
