Thanks, added my voice to that chorus :)

Would definitely like to see this implemented.  I use dropbox for both writing and sharing code snippets, so having to manually sync each time I make an edit is a bit of a pain. :)

I know this is an old thread, but I too wanted to echo the request to enable automatic Dropbox syncing.  I want to use Textastic for both coding and writing, and I love the automatic syncing in Elements and Notesy.  Can we re-open this or open a new request for automatic syncing?
