Make categories or links invisible

It would be nice to be able to disable a category or link and make it invisible so it won't show up on the pages without having to delete it. Let's say you are working on a brand new category but don't want to make it active until it's totally completed with links or if you just want to disable a category for whatever reason. A nice little checkbox that says "invisible" or something like that will disable it.

Also, a mass copy feature. I have a lot of categories and there are a lot of different links that belong to many different categories. It takes a lot of clicking and time sometimes to copy a link to 20 different categories. A mass copy feature would be a dream come true.

Thanks
