Are you ever looking at a web page with great information but want to find out if there's a simple, more easily digestible version in video form? That's when it comes time to search on YouTube -- except then you have to make another window or tab or leave the web page to perform that search. Search On YouTube is a Chrome extension that puts a tiny little YouTube viewer in your toolbar so you can search easily and trouble-free.
Once you install the extension you just click on its icon to bring up the search panel. Type in what you want, see a bunch of videos in the bottom row, and click on to watch it. It's a much simpler YouTube-viewing experience that you can manage without dealing with an entire browser tab or any of the other stuff on YouTube that you don't necessarily need.
