is there any chance at all in the near future You may consider introducing to the laytheme the REM unit not just as a type-size unit, but more like a general unit used to size and scale also page elements and paddings/ margins etc .. so that everything can be proportional and reference back to the same value established at the root level of the site? how great would that be? I hope I am not the only one who would love to see this happening ........ I'd love to be able to assign paddings and margins equal to the height of a line-height or two without using px (non-scalable)
