A notable feature is the ability to synchronize code selection with visual selection in the preview. Since this extension has minimal functionality, the codebase is very small, making future expansions easy. It is designed to reflect changes made in the preview back to the code, so enhancing the editing capabilities within the preview may be beneficial in the future.
It doesn't matter if it's complex. I believe this tool can be applied if it consists of a single HTML file and the resources linked to it. If you're using Web Components, there may be some issues. JavaScript is currently disabled because it's difficult to determine its impact, but enabling it is technically very simple. If there is enough demand in the future, I will add an option to control the functionality of JavaScript.
Because I don't understand the template language used by Hugo. The syntax is weird, using features is complicated. Everytime i thinking of changing something in my site, it feels like PTSD thinking about touching that code.
If it was just html, I could modify it easily. But doing big structural changes in many html files is as painful. Visual tools, like this one should help with that.
