First thanks for the free Quasar version. Gives me a chance to play with Magento again and that can only be good for you guys so kudos to you Sam and the team for doing this.
So question 1, im only playing with the free version, how do I change the style from 6 to something else.?
Go to System -> Configuration -> Design and then change where you see "style6" to whichever you want - 2, 4 & 6 are light styles, 1,3 & 5 are dark - so if you want a dark style, also change "light" to "dark".
STEP 1 IN MAGENTO DEVELOPMENT - DISABLE YOUR CACHE OR YOU WON'T SEE ANY CHANGES.
