I loved Markdown New Tab (a web extension that open an editable markdown page on new tab) but wanted to add widgets like weather, which it couldn't do since extensions can't execute userscripts. So I built Mencrouche, a hackable homepage where you can add bookmarks, markdown notes, images, or any custom widget by just pasting code into custom JS textarea. No cloning repos or installing anything.While building this, I try not to use frameworks like React and found it's actually easier to manage state with plain variables and direct DOM manipulation. I ended up writing my own libraries for translation, DOM aliases, and undo/redo.
Currently it's just a web page since I'm struggling with manifest V3 for the web extension version.
