 - `Improvements` - Add code of conduct
 - `Improvements` - Disabled useCapture flag for a block keydown handling. That will allow plugins to override keydown and stop event propagation, for example, to make own Tab behavior.
 - `Improvements` - All modules now might have `destroy` method called on Editor.js destroy
+- `Improvements` - Block settings can contain text inputs, focus will be restored after settings closed [#1090](https://github.com/codex-team/editor.js/issues/1090)
