I am really liking the new Arcade pop-up element, only I wish there was a way to set visible/not visible. Currently the only option to hide an arcade element is to delete it.
That means starting over if I want to add it back and makes it very hard to modify a map already in production. With the traditional arcade expressions, I can work on the expression, and it only shows in the pop-up once I add it to the pop-up. Pop-up elements are always added to the pop-up results.
If I had an eyeball toggle like layers, I could easily just turn it off and on.
