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.
Agree. And this is the first OSS keyboard I’ve found that can do multiple languages at the same time without switching the language/layout. (You can set secondary language) It requires a bit of setup (like downloading dictionaries) but I’d suggest to give it a try.
