After the post I made last week announcing the first version, I received lots of useful criticism and feedback of my product, Trolley - both on the landing page content and the app itself.
Based on that, and the feedback I got from a Show HN post too, I've been iterating like crazy.
I finally managed to push out the latest version tonight, along with landing page changes (including a demo video, which was mentioned by several contributors).
I just wanted to say thanks to everyone who helped with feedback - this is a great community :)
