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.
Just installed it. Adjusted the settings to my liking. Very nice. Like OpenBoard, but has quite a lot of extras by comparison. Thanks for the tip.
