Also, thanks for the markdown support. I'm one of those weird people that will ask if you'd be willing to support org mode as well. And I'm kinda surprised you don't if you use it yourself! I'd be very likely to use this if I could simply point it to an org file and have it displayed nicely on the web. I often take short notes that turn into long notes or vice-versa.
A fair response to your question would be, "submit a pull request" (thanks for being open source)... but I've got far too much science to do at the moment. So, regardless, thanks for building something cool!
