We have seen the future and it's far more flexible. Specifically, the lack of modules in Guided Landing Pages makes them very rigid and requires users to create many templates that are all very similar, just with different modules in different display orders within the same landing page template.
It's gotten to the point where we are considering guiding our clients to use Squarespace, Weebly or another CMS on a different subdomain to create landing pages because the UI is so much more flexible while still removing the limitations of free-form landing pages.
It stands to reason that the updates we saw in Email Editor 2.0 would be ported to Guided Landing Pages, but the question is when. If it's soon, we can tell our clients to keep patient. If it's a ways off, we may need to make a move. Has anyone heard anything about an update from Marketo? How are you navigating templates?
