The order of operation for "highlight" and "insert text" is inconsistent.
When highlighting in the newest version of Reader Pro, one may select the highlight feature and then highlight the text, just as one would do with a physical highlighter. When using the commenting feature to insert additional text, however, one must first place the cursor in the desired location and *then* select the insert text feature. This seems inconsistent with the highlight feature. I don't recall this being the case in the previous version and I'm having trouble getting use to the change. (One of many.)
