I have been using AnySoft, but its so buggy at this point, its effectively unusable. Judging by the github, its been in this state for at least a year now. I tried to downgrade to an older version in the hopes of fixing it, but couldn’t get it to install. Is there any better options?
I used thumbkey for a couple months. I could use it, but it was never fast. YMMV
By fast I mean by touchscreen keyboard standards about 20-30 wpm.
