I wrote a chrome extension called Symplie that lets you write and view notes in Markdown: https://chrome.google.com/webstore/detail/symplie/kjadigajmc...

Pretty sharp. I like the preview toggle - seems to me that keeping the preview visable all the time like other editors is a waste of space.

Since it saves to Chrome local storage, wouldn't notes get synced along with other Chrome data?

I'm actually just using IndexedDB so it doesn't sync. I use Chrome storage to cache the license (in case you were wondering about the permissions). There is a special Chrome storage sync api but it's limited to 800kb I think. I'm still exploring a good way to implement (unlimited) sync. Thanks for the feedback!
