Any update on this? I have fifteen btsync folders configured specifically so I can take advantage of this if its ever implemented. For the moment, I am constantly removing folders from one device or another(within btsync, not the folder itself) that I don't want to have priority and re-adding them later. It is truly a pain that there is no way to tell btsync what should be transferred or when.
. Same here. Exact same usage scenario even. This is the definition of backup to me, and even though I've set trash_ttl=0, I don't like having to dive into .syncarchive to then move files to a sync-folder not affiliated with my phone.
