Ever visit a website and wish you could remember where your bookmarks are for that site? Saved a post from a blog and can't find it? Find My Bookmarks is a Chrome Extension that locates all your bookmarks for the current domain. If bookmarks are found, the icon appears and you can just click on it to get a list.
The idea for this came about after a discussion with a coworker regarding bookmarks. That night I went home and 2 hours later I had a fully working prototype. Another hour later and a bit more polish we were ready to release it.
Now I can say I built a chrome plugin. Not that I actually need or use it, but it's a nice portfolio item.
