Best editor for markdown and code for Dropbox

I have the new Coda, Textastic, Writer, 1Writer, Elements, Nebulous notes, iawriter... This is the app I use most frequently to to edit code and markdown in Dropbox. It is largely bug free, has excellent Dropbox support, and the editor is capable but very simple to use. The simplicity of the interface is a delight compared to some other apps, without compromising functionality. The only thing missing is an easier way to add ssh key for Sftp and ssh connections. Otherwise this app is a gem. I highly recommend this under appreciated editor.
