Would love to see some rule features for non-continuous sync. Some examples might be: sync once per hour, sync only during this specific time, or sync continuous during this period but not during another time period.
The specific use for me is that I occasionally am running software which makes a lot of temporary changes that don’t all need to be synced. Disallowing file types isn’t plausible because I do still need those to be occasionally synced. Blacklist seems to leave lots of files in “waiting”, “not allowed”, or “trash bin” (even with auto-empty trash enabled). But I digress.
