Is there a way to create the effect of pinned/fixed elements? (i.e having a button that stays always at the top of the page even when users is scrolling down the page)
A lot has been going on since you wrote. I'm glad to tell you that our current version supports scrollable containers. Here you can find more information about this feature.
Once again, thank you for helping us make Indigo better. If you have any questions or more feedback about the product, we'd love to get your thoughts.
