[Test Idea:nested shares]

It does!

I'm curious as to how you managed to get it working.

Using 1.1.15 right now, I can't seem to setup nested shares relying on the .SyncIgnore trick, with a directory hierarchy like this:

/Shared/.IgnoreMe/.IgnoreMeToo/ToShare/

Created a first share "Shared", which has a .SyncIgnore defined to ignore ".Ignore*" patterns (and it works, as evidenced by .Ignore* folders not being synced across machines). Still, creating a second share for "ToShare" results in the infamous error message about nested shared folders blah blah.

I'm surprised there's been little if any improvement ever since the issue was raised - it's indeed a dealbreaker.

Using it to backup 500+ GB of local data from my local Windows PC to a distant server (with btsync as a service under Ubuntu). No issue so far, works great and snappy
