I reckoned it would be a one time thing - so I invested some time in the Jade logic to mimic my MODX ifs and thens.
I used blocks so that I could get a fairly working preview offline
if slider == "yes"
[[+slider:is=`yes`:then=`
.bigTitleBG.shiftMe
.container
block sliderM
`]]
if h2Content == "yes"
[[+slider:is=`pagetitle`:then=`
.bigTitleBG
.intros
[[+neighbourNav]]
And since, as you know, in Jade, you don't need to close HTML tags, high speeds can be reached.
It was fun. And connected to SublimeText, it was cool.
