*Adding new expressions:*
Currently it's impossible to add new expressions between two already existing
expressions by clicking with the mouse in the area between those two
expressions. It's not possible to add a new expression at the very top or at
the very bottom of the worksheet, neither. Mathemica and wxMaxima can do this.
In Cantor there is only the short-cut "ctrt+return" to add a new item after
the currently selected one. But this is not flexible enough. It would be great
to have a "tolerance area" of couple of pixels aroung each item. By hiting
this are with the mouse a new item should be produced.
Sometimes you want to highlight a certain expression by changing its font
(size and color) or to change the background color. Or you want to add an
empty line and to change its color to indicate a certain logical separation in
your calculations. If I see it correctly, Cantor currently lacks any kind of
formatting like this. Mathematica can do this.
Sidenote: when starting Cantor in the terminal, the terminal is full of debug-
messages like QRectF(80,156 1x47) QRectF(0,0 677x584). Are they really
