Would like to see access levels provide permissions for additional items, such as "using search", jukebox mode, upload/download files, etc..., in addition to folder permissions.
This would make it easier to create users on the fly (using the script), and automatically have the correct permissions granted based on what group the user was added to.
For example, if I add a user in the "Limited" group, I don't want them downloading files (streaming only), but if I add the user to the "Family" group, then I would allow downloading files.
