Things to do before GUI-developers can start their work



Another thing worth mentioning on this thread is the Emacs Calculator,
since it can do some algebraic manipulations, simplification, etc.  It
has a not too shabby stack calculator interface, where you can arrow up
into the stack, and select subexpressions that can then be copied to the
top of the stack.  IMO, that's not a bad interface at all.
