The current measure polygon feature tool measures, as far as I can tell, the highest feature in the layer hierarchy. I on occasion produce ArcReader viewer software for non-spatial professionals. They may find it difficult to understand the layer hierarchy and the need to have the feature they are querying as the highest layer switched on, or that the local government area layer is switched on even though only a label can be seen.
It would be useful for the ArcReader user if the measure feature tool measured say on the layer selected in the layer effects toolbar, or had its own independent feature layer selection option.
Also the highlighter tool would be useful if it had snapping and text capabilities.
