Optimization of Mark Editor's Selection Functionality #972
Description
Suggestion for Improving Mark Editor's Selection Feature
- I use the default Asciidoctor preview template.
- Currently, the selected portion in the editor (or the paragraph containing the cursor) does not display a vertical indicator bar on its left side—even though this bar does appear when using VS Code's default theme.
After reviewing the source code, I noticed that the current implementation of this feature does not guarantee consistent behavior across all possible preview CSS templates.
I believe that if an HTML element in the preview pane is visible, it must occupy some space on the page. Under this assumption, a more robust and consistent way to implement the Mark Editor's Selection feature would be to highlight the background color of the corresponding HTML element.
Changing the background color would only fail in one scenario: when the highlight color is identical to the template’s background color.
I’ve implemented a prototype of this approach, and a screenshot is attached below:
I’d like to suggest adding this functionality to the plugin: highlight the selected region by changing its background color.
