Make everything important on the page stay inside an area of the same width that the GeoGebra canvas has.

It will help in making self-sufficient screenshots (those that have both problem and solution in them), without having to include any unnecessary area of the page.

Another neat thing would be to make the page layout consistent across different tasks. That is, to make each page element (problem desc., solved sample, GeoG box, copyrights and info under it etc) always stay in the same coordinate boundaries.

Concur. Excellent presentation! Also smaller example images to assist present the game space as visible, immediate and consistently as possible.
