Since due to selective sync and syncignore, files doesn't necessarily exist on all connected hosts, it would be useful to know the current redundancy of a file in the sync folder. We're working on a decentralized storage of our data on several computers. If a file only exists on a single host (all other hosts ignore it) that host should know that. Deleting it would be bad then... :-) So, the get_files api method should include a field "availability". A new method "get_file_peers" could return all peers, that currently share this file. Another selective sync feature: searching for files. Currently you have to browse the "virtual tree" recursively via get_files to search for a specific file. I'm sure, the client could to this much faster. A find_file api method could return an entry similar to the get_files items (almost... it must include a "path" entry) if a file exists... or an empty object, if not. And... yes, why not... what about a find_files_regex method?
