You are right, and this is something that made me uncomfortable while
writing the spec.

Ideally this should be very similar to the interface the gsearchtool
uses, or to the one Beagle will use --- as Alex said, it may just be
better to let Beagle display its fancy tiles, rather than try to stick
everything in a tree view.

Being able to define which columns get shown in the stock file chooser's
tree view sounds like overkill; we may do better by just letting
extensions completely override the display.  An extension would need a
method such as ::gimme_selected_paths().

It would handle *that* just fine.  The idea is to put the extension's
extra widget right above the place where application-specific extra
widgets would appear, which is the place you want.
