Just checked the forum after being away for a year or so, to decide if I have to upgrade to new btsync version (I was sporadically using 1.3 or so) to find _THIS_. I'd reckon I'd pay 40 bucks or so for a software, but I'm not buying subscription. I was using btsync to keep backups of my photos, so I'll be moving to rsync for now. Need to consider Amazon's unlimited cloud drive offer too.
I'd like to see this implemented as well.
