It's not flexible and fast enough. It's much easier to click between
expressions to produce a new one then to go via the context menu. In text
processing you don't go via the context menu if you want to add new letters
between already existing letters - you just click in the text and start
typing at the place where you want to add new text. Similar for CAS, you click
between two expressions, you set your cursor so to say, and then a new field
for expression is produced when you start typing.
In this screenshot you can see the horizontal line between two expressions.
Such a line indicates where your "expression cursor" currently is. If you
start typing, a new input will be produced at this place:
Similarly it is solved in wxMaxima, too.

Yes, they do. Sometimes you want to annotate some important steps in the
calculation by just coloring the corresponding block. Or you work with colors
and different font sizes to separate different regions in a longer
calculation, etc. Actually, the internal documentation of mathematica consists
of many read-only notebooks (workbook in Cantor's speech) where one can see a
lot of different formatting and grouping features that allow to produce such a
documentation. All those features are available to the user in the notebook,
too. Here is notebook with some basic formatting http://imgur.com/H2WZ9i0
