shared selection (internal and external)

It would be great if users could select elements in a view (say the tree view) and then:

• Open that selection in another view (internal)
  • E.G. via click+drag or an "open in X view" menu button.
• Share an external link to those elements with other people (external)

This requires a standard way for views to store their selection.

The universal ID gives us a convenient way to generate portable lists of selected elements.

I'm thinking that the easiest way to do this might be via a "share" menu button which might give you a link like:

/whatever/open?view=tree?selection=~user/flow//cycle/task1,~user/flow//cycle/task2,~user/flow//cycle/task2/job1

We could potentially do something with the URL, however, due to the multiple tabs layout that will unlikely be suitable for sharing?
