I think Insight does this but ISTR Totalview uses a separate frame.  Expanding
in situ makes it harder to find the other locals.  In fact I'm thinking of
using a separate frame for each watch expression, something which isn't really
possible with the speedbar.  This would be helpful for arrays and large
structures.

The GDB command "watch" means something else (it sets watchpoint, rather than
creating a "watch expression").  Watch expressions are created using something
GDB calls "Variable Objects" and they are created using GDB/MI commands
intended for the frontend only.  I'm not sure that there is much benefit in
making this functionality available to the command line.  Note if you want
to supply an argument for a watch expression, you can do C-u C-c C-w from the
GUD buffer or C-u C-x C-a C-w from any other.
