I've been testing with the new new Android app (I'm using the version published in the Play Store yesterday) and wanted to give some feedback. There are a couple of confusing elements in the UI: 1. What's the difference between the "Sync" tab and the "Backup" tab? 2. When setting up a sync folder, there's an option to "Automatic sync". I guess it means that remote files are downloaded automatically, but the option isn't really self-explanatory. The ability to send files is great, but it's a bit difficult to use - you have to open the app on both sender and receiver and browse for the specific file. It'd be great if you could make at least the sender's life easier by making BtSync a share target, so it appears in the share menu when you want to share data from any app (like Dropbox, or Gmail do). On that note, it'd also be nice if you could share a file directly to one of your existing shared folders (say, to send the file to your PC). Otherwise it's looking great, and better yet - working great!
