Just figured out yesterday that OpenBoard is abandoned and jumped over to Heliboard, thanks to the announcement for 1.0 in this community. The top comment mentioning FUTO Voice Input, was also a great find.
The only annoying part is that I now have to retrain my recommendations for HB, since OB unlike HB, offers no way to extract your settings, and I found no method to access the settings files in newer Android. Thankfully, since HB offers import/export, it will be the last time.
Btw, mineclone2 also rebranded as Voxelibre, months ago, and for the same reasons. Voxelibre now actively moves away from copying Minecraft exactly.
If you want the closest copy (and my personal recommendation) check out Mineclonia.
