Change name folders homecontainer

[Fenderbassplayer]

Hi, first of all thank you for this wonderful software!
I have a few newbie questions:
- Is it possible to change the names of the album and item folder in the homecontainer? For example I would like to change the album folder to Albums and items to Songs or Morceaux and if possible omit the <n> count.
- Is it possible to blacklist clients (like in de DSM mediaserver) to prevent other Upnp compatible machines picking it up?
