ksattic: "I've got Impression Style and Publisher and have never noticed the tabling feature."
It's more like glorified tabs with line drawing hacked into the style system. Minimal effort for, well, minimal effect.
Meanwhile, the Windows demo of Ovation Pro was impressive in certain respects - irregular frame shapes, etc. - but he's going to need to improve the user interface substantially. And, yes, that means following the platform user interface guidelines rather than foisting some kind of RISC OS look-and-feel onto the hapless users.
