We just put together a video that goes through each responsive option one by one and shows what it does, and when to use it. It’s a little bit more academic than the video @brentsum put together (it’s about 17 minutes), but it’s a good way to see the different settings you can use.
With this video (and an email to the whole user base sent soon), we’re officially out of beta for our responsive engine! Thank you everyone for the feedbacks, bug reporting, and help in general to improve the feature. While we’re out of beta, we’ll keep on improving things as new needs come, so, as usual, let us know if you think some stuff could be done better!
