Just give me a simple expanding text entry option with save on return

It would be nice to be able add in a comment field that expends on text input but when you hit Return it saves, without having to add button in a group and use a single line text input.

  1. Single text input to do this without the submit button in a group.
  2. Turn off Return (paragraph) on multi-text input so it still expands line by line on text entry but Return key results in a save - without a button.

Reference - Facebook comment field.

You can add a condition that is “value changed” of your input and then it triggers a workflow. Another alternative is to autobind the input to your DB, which will make updates virtually character by character. Either solution avoids a “Submit” button.
