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.
Really? Maybe it works better for some languages than others, but the majority of what I type on my phone (outside Lemmy) is in Frenglish and Heliboard handles it really well. Have you tried switching which one is set as the primary language? With the most recent update, I was having issues until I changed my primary language to French and the secondary to English.
