[FEATURE REQUEST] Realtime Sync only processes notified file path

[Moisie]

Hello:

I've thought this through, and I think it's a valid and workable request:

Assuming Realtime Sync gets passed a useful filepath from inotify (or whatever the underlying filesystem watcher is), then could Realtime Sync only process that given filepath (or its parent - whichever seems more robust)?

This would effectively be temporarily passing the filepath as an Include, and * as an Exclude to the appropriate FFS document.

The advantages here would be:
- Much faster sync performance on a large data set;
- The ability for Idle timeouts to only apply to a subset of the 'top-level' folder pair, allowing one subfolder to sync without activity in a different subfolder blocking it.

I know I would personally find this very useful - I hope it's worthy of consideration for inclusion!

Thanks.
