layout generator?

In putting together my first script (modifying the sendstorm script — thanks!!) I realized it would be great if one could easily create a layout image showing the knob and button assignments for each mode — similar to the layouts provided for the sendstorm script as attached.

This may be asking too much, but would it be possible to have an automatic layout generator as part of CSS so that when the community creates and shares scripts that the layout is also a part of it?
