Sorry for the delay, pulled away on another project.....
The rulers help, and the alignment guides for complete objects continue to work as usual (previous versions) however if you take a 'draw with pen' shape in '09 and select an individual control point, there is an alignment guide/snap to option to set that point into alignment with neighbouring points (de-selectable by holding down the command key while adjusting). Default colour for those guides was yellow, as seen in the attached screen shot from an '09 example.
I can't find an option anymore to enable this. Thoughts?
