The whole sharing UI needs a revamp

Managing shared folders and permissions on dropbox is extremely painful and needs an urgent revamp.

Sharing a folder is fine, but as soon as you have multiple shared folders which are shared with multiple people where not everyone has access to everything it becomes a nightmare to manage.

There is no way to see which folders a "User" has access to so if you want to unshare all folders with a specific user the only way I have found is to go through each and every shared folder you have to check if that person is on the share list. If this could be done from one screen it would be acceptable but currently you have to drill down and it can take ages.

I would like one screen where I can see all shares (as is the case now) but clicking on a folder shows all people that have access, on the same screen, with an easy way to manage. Select multiple and remove them all at once etc. At the same time, I would like to see the reverse so a list of people who have access to shared folders and in one click see what they have access to and manage that.

What would also be nice is to permission groups, so instead of sharing multiple folders with a person I can just add them to a group that has access to those folders. And again, an easy and intuitive way of managing this.
