I have just started using SMath Studio and I am very impressed with functionality & stability of the program.
Great work, many thanks to all who have contributed to the program, plugins & excellent tutorial material.
I have one suggestion to make: I think it would be useful to have a printer page tiling guide line, that could be switched on/ off as desired.
Alternatively, if the canvas were to resize to the printer page, it would stop you typing outside the print area.
If I print a document with text too far to the right, it does not get printed.
At present you have to use the print preview to judge if you are working on the printable area.
These suggestions are only really an issue if you are working on a document that is to be viewed as a paper copy.

Kind regards
jim
