I'm very excited for the iOS app to finally be available. I have set up my first sync folder and it's working great. In other syncing apps, like Dropbox and Copy, I'm able to upload files from other apps to my sync folders. For example, I have this app called iDownloads+ that allows me to download files from a browser, then I can click the file and it gives me a bunch of options to Open in other programs. I don't see an option to Open in Bittorrent Sync and add the file to a sync folder. I don't know anything about iOS development, but I'm really hoping this feature can be added!
