Somewhat ok. Could be significantly better.
The local http server to serve the files is very useful. However it’s lacking a lot of features - e.g. when allowed access to photos it still “imports” the files from the library, effectively copying them and thus doubling storage requirements. ssh/sftp and/or cifs access would be great. NFS is clearly beyond even the wish list… The UI also leaves a lot to be desired. Free version must be useful, not just the Pro one.
