For those of us that have a site collection URL and install DFFS at the root it would be nice to have the Site base URL be a drop down (defaulted to the root site) where you could select your child site instead of entering it. Just a nice to have feature.
The reason for not having it in the default version is that you must have site collection admin rights to be able to enumerate all the subsites and I didn’t want to complicate it with two different methods, but it’s a good idea, I’ll see if I can add that in a later release.
