Welcome back Julian,
I've split your reply (with the replies) from Mary's Look and learn because it is going off topic! However needs to be kept, so a better title.
If you look at most of the themes here, you'll see that quite a few have my code in them that I've developed over the years in Essential and my other themes to add functionality. I hope you'll understand why I stopped Essential development. Sometimes you can only refactor and improve so much before you need to start again. Hence my Foundation theme.
Kind regards,
Gareth
