Support the upload and sync of any file formats (without previews and version comparision)
It would be perfect if it would be possible to upload every needed working file of a project. I'm using overflow in example to create flowcharts for my sketch files. ".overflow" files are not supported, but I would like to upload those files to have all project-related working files at one place. I would put up with having no previews of this files and no version comparision and so on.
