Hi. Some people, like me, use BTSYNC for broadcasting video records. We use BTSYNC like this: One or a few people have all permission as well as others, most of all, have only readonly permission. We need 2 more functions: 1 Avoiding re-download. If some files are removed from the computer with readonly permission, please do not re-download them back. 2 Choose to download. Okay, this is not important. Maybe there should be some way to let all clients choose which they want to download within all shared files. Thanks.
