I have just recently started uploading files to my SD card through Octoprint after noticing much better print quality using this method, and a quirk appeared in OctoRant on the latest version of OctoPrint as of time of writing- the Upload to SD prompt uses the same percentage progress bar as a normal print process, and it sends Printing Progress messages out with screenshots even though no print is in progress. Instead screenshots/messages are posted at SD card file upload intervals matching the "notify every xx%" print progress interval.
