  3. …more or less the philosophy of the editor I've been working on (and using ~exclusively) since 2014: https://github.com/alefore/edge/tree/master Some parts of the UI are still defined in the compiled language (so don't fully fit your…

  4. In my text editor ( https://github.com/alefore/edge ) I keep the undo/redo history always linear, which I find works pretty well. So suppose the user does the following operations: • Insert "Hello" • Insert " world!" • Undo once. • Insert…
