OK, I'll add it to the wishlist :-)

Hello,
I find your program very useful!

What I would like to see in a future versions it the ability to filter the path of synchronized directories...

It could be some kind of exclude filter, so that some of subdirectories were not synchronized...

Files to exclude:
"pics/*"

That would mean that no files that are in pics directory are synchronized...

Best regards,
Piotr Szczepanik
