Darn it, I popped into this thread to suggest Thumb-Key, and was beaten to it by the maker of the keyboard!

Thank you for making my phone usage much faster and enjoyable (written using Thumb-Key of course!) :)

Thank you for sharing this! I have enjoyed thumbkey for a long while, but it’s lovely being back on qwerty to try this out :) at minimum it means I have a keyboard to offer when other people use my phone! :)

Thank you for mentioning /e/os, this is the first I’ve heard of it and it looks like a nice open source os without making using it a chore! 😁

I might give it a go over the weekend once I’ve backed up everything. 😊
