I don’t know who can realise this feature Request.
I would like to have the ability to open the style settings of Foundation 6 in a separate window and watch the Preview of the page in another. It would great to see every change of a style setting directly.
Especially when you work with styles as a partial you have to save the changes, open the preview mode and then go back for every little change.
I am not sure, if this is future request für Foundation 6, Stacks or Rapidweaver.
I wish you alls the best for 2021!
