Congratulations for the excellent sync to Dropbox feature. However I don't want to buy additional space in Dropbox because I am already extensively using Google Drive, which by the way is cheaper.
Do you plan to support a "sync to Google Drive" feature as well?
Glad you are enjoying the Dropbox feature. We do hope to have Google Drive as an option, and we don't have a concrete date for when, but it's on the list of features we wish to add. Thank you for your interest in O'Reilly books and have a great day!
