Nice work (and great name) by Jeff Mueller: starting from my idea for an action menu for Safari in Launch Center Pro, he made a web app to simplify the process of assembling the bookmarklet. You can choose from a set of emojis for icons, select one of the built-in actions (so you don’t have to write URL schemes), and hit Create Menu to generate a menu. It’s very simple and much better than writing code manually.
I hope that Jeff will add more app actions and emojis soon. Check it out here.
