That would seem the obvious solution and is the case in other IDEs. e.g
you see "p" in the locals (where p is a pointer to a struct for example)
and then can see the struct by double clicking it for example. Pretty
much what the speedbar does but without the speed bar. (As an aside, if
I mouseclick 2 on a local in the locals buffer then its added to the
speedbar as a watch - it would be more consistent I think if "watch p"
from the gdb command line also did the same if the speedbar is in use,
what do you think?).

A tree view would be nice in the locals pane or a special watch pane.

Some do, but they are not convenient or "static" enough. If I have a
pointer in a loop and step around the loop I would like, reasonably
enough I think, to see the pointed to structure change as "p" changes or
its dereferenced contents change. Certainly a tooltip is not the best
for a struct of more than one or two elements.
