Mosh: implement the “--predict-overwrite” option on the client
I’m assuming Termius doesn’t use the mosh client itself but rather its own client implementation.
The official mosh client supports the option “--predict-overwrite” which will overwrite the current line/command with the predicted text rather than inserting it to the right of the cursor.
Using fish shell and the default prediction behavior is really not a great user experience, to the point where I find it unbearable myself—see https://github.com/mobile-shell/mosh/issues/932. Turning on “--predict-overwrite” is such a huge improvement. It would be really great if Termius had that option too!
