Honestly, I found the UX to be very confusing. Some basic things -- The highlight to select an element is inconsistent. Sometimes it is a padded highlight, other times it isn't. The instructions to "right click" don't make sense on a mac and the usual cmd+click doesn't appear to do anything. Other times, there is no selected element, I'm scrolling through the left bar to pick something to add, yet the UI remains with the appearance of something selected (blue outline). In short, the selection/action/deselect was not intuitive for me. The first thing I tried to do was drag a button into a column section -- nothing happened.
