“Hidden” fields are...hidden to the form fillers, but to the one who creates the form they are visible - added like any other element (via drag & drop) and take up space on the canvas.
Where’s the problem, you ask? Well, there are users that find these pink elements on canvas distracting when they’re building their form, and they don't want to be bothered with finding a place for each hidden element on canvas (especially when there are many of them).
So in this version, we’ve made it possible to work differently with hidden fields.
You can make sure the hiddens don’t show on canvas and manage them in a Tree view structure.

Enjoy!
