Use one Bookmarks window for all documents

[humdingerb]

Currently, every open document has its own Bookmarks window.
It'd be nice to have one single Bookmarks window (with a normal look/feel) for all documents and only change the contents according to the active document. That way you could tile the Bookmarks to the document window, and even if you don't, the Bookmarks windows wouldn't jump around if you've moved the Bookmarks window of one document but not another.

How do you use it?
The way you want it to work doesn't make much sense to me. Why would you want it docked at all times? I see it as a management interface you start because you need to cleanup or get an overview, not something to have open all the time.
If you add toggling with a button, it creates a lot of headache tracking the state of the buttons for all windows. (Although it is doable.)

I may be abusing the bookmark feature to emulate Pe's f(x) popup menu that shows/jumps to all classes in a source file. The single feature I still miss dearly. :)
