Flex Note for Chrome
More About Flex Note
It's open source and you can get the source code form https://github.com/yguan/notepad. You can also try it out on the web before installing it (http://yguan.github.io/repos/flexnote/#/notes).
I also packaged this app as a desktop app, and you can get it from https://chrome.google.com/webstore/detail/flex-note/acndffknklaklnnpjmdbfknnohmikcje.
