THAT is bloody MAGNIFICENT, Paul!
EXACTLY what I was looking for! Thanks so much!
Ironically I actually did have a gander at the 'Crisp' theme, but never the 'Crisp_play', so I missed these great enhancements.

...and while I'm in gratitude-mode: thanks also for compiling the very informative "Creating themes and templates" documentation. Very informative, even for a DB/programming n00b such as myself. I wanted to show some recognition for that earlier on, but never got round to it... :-[

Thanks again!!
