I would like to be able to remove items from the sidebar such as 'sites, membership, app marketplace' so that they are not visible at all for the user/client. Just to make things less confusing. I especially don't really want them clicking around in the app marketplace, or at least specific clients I may not want them doing that.

I'd also like to be able to sort them different, for example, I have a custom link for running ads and I would like for that to appear at the very top. If we could move them around would be great.
