Does plex finally support reading files from network shares?

Plex is based on XBMC (aka Kodi), which supports reading from the network natively, which leads me to believe they disabled this on purpose and I've never understood the rationale behind it. It makes plex almost useless to me and anyone else who uses a nas or similar to store files. Expecting that I will run plex itself from my nas because they disabled network access is laughable.

Also their UI has consistently been going downhill for the last several versions.
