It appears there’s a PR for gestures already, but there’s a non-zero probability it won’t be merged because of unexpected patents out of all things. Wonderful.

Yes, because I consider how the keyboard feels too. FlorisBoard felt better than Heliboard to my brain. And its action bar can be configured to always display above the correction bar.

Thank you, I’ve given it a try. It feels less bad than the other options I tried, probably forking it and adding missing gestures and small improvements could improve it much more. But text correction is still like in Heliboard.

Should be doable with Termux:

1. https://f-droid.org/packages/com.termux (the terminal emulator itself);
2. https://f-droid.org/packages/com.termux.api (for termux-sms-list and termux-sms-send commands);
3. https://f-droid.org/packages/com.termux.boot (to make the script launch automatically after reboots; don’t forget a wake lock to keep the process alive).

termux-sms-list returns messages in JSON, which is easy enough to handle with, say, jq in bash or json in python. The script itself can be a simple loop that fetches the latest messages every few minutes, filters for unprocessed ones from whitelisted numbers and calls termux-sms-send.

Maybe it’d make sense to daemonise the script and launch it via sv.

But the Termux app weighs quite a bit itself.
