I would like to see an option on the Windows version that would configure operation so that it only retrieves the index of filenames from the remote system(s) but does not download the actual file unless the file is requested by the user. I believe the Android Mobile version operates in much the same way. It is quite easy to lose track of how large the sync folder may become, especially if you have one system with a huge hard disk. If other systems are connected that don't have that much space available, it would be too easy to overfill the smaller hard disk. If the program on the small capacity system could be configured to keep the list of files updated with the other systems but not actually download the files until needed, it would reduce the risk of running out of space on the hard disk. Thanks for your consideration!
