Since yesterday, the really cool fork of openboard with active development and support of adding a swype library manually, got rebranded into Heliboard. A release on izzyondroidrepo and fdroid should be coming soon.
PS. If you are using the old fork you have to remove it first and do a backup of your settings.
I had to stop using it for English even because its word predictions were horrible. Very common words kept correcting to much less common words on a regular basis. I gave it a good three months and I just can’t do it. Wanted to like it so much.
