I'm also interested in this. MessageAse was my daily driver keyboard until some bugs appeared, then I switched to Multiling O (here's my messagease inspired layout https://github.com/racuna/multiling-o-esbr https://github.com/racuna/multiling-o-esbr ) but is also abandoned with not fixed bugs. Now I'm using thumb-key as my daily keyboard but waiting for them to add more features, or just jump to another keyboard app.
