Google video - What I wish it had

Google video is a great tool. However I think it is still at "friend" level of relationship with the reader.

Below are few examples I imagined, that could make it to "family" level.

1. Rating filter (PG, G, PG 13 etc)
2. XML to subscribe to the source
3. Opinions
4. Tagging
5. Saving (Which I think has been rolled by Google !!)

Can someone please inform Google !!
