Hoisting, multiple trees, tree clutter - User feedback welcome...

[srdiamond]

I'm not sure I understand "separate, independent, trees." Let's say there's a tree T1 with immediate children A, B, and C.

How would this differ from having three separate trees, Ta, Tb, and Tc, where Ta contains all and only the infoitems and their relationship in subtree A, etc?

It seems to be a hoist on subtree A is exactly equivalent in substance to opening as a tab the tree Ta. The approaches are exactly the same, just as long as the separate tree approach allows you to have more than a single tree open at a time.

But the hoisting approach has the interface advantage of being implemented from the menu and/or right-click, leaving tabs available for a multi-page interface, where several infoitems can be open at the same time. (Not sure if that's "on the list.")
