Well, by chance, I too am just starting to edit my site after a long absence. Did check in Admin in case I had missed whether update had been issued (wasn’t paying attention to the forum). Alas, here’s your email.
Wasn’t too comfortable with tab versus popup because I can move a window over and view the record whereas with tab, I have to go back/forth (for details on info or names, etc) I know comment was made about size of the popup but usually not a problem. But, maybe using feature may change how I feel, not sure.
