There is nothing wrong with the OS.  It handles many other programs without
a problem.  The Mathematica FrontEnd implementation on Linux is 1995

I don't find it very well structured.

Those are all presentational matters, and not directly related to the
structure of the notebook, other than the fact that the features operate on
parts of the notebook.

I would like to see support of XML document specifications, and stylesheet
which function orthogonally to the content.  Ideally, I would like to be
able to change stylesheets, and have vectors change representation from
bold face, to over arrow, for example.  A vector should be tagged as a
vector and the form of presentation should be determined by the rendering

An example of how a pallet can be useful is finding the name for a
particular symbol, and also the keyboard shortcut for entering the symbol.
