Feature Request: Add Field Popup support for all fields...

[theperfectwill]

It would be nice to be able to use the popup feature for any field. Like below.

Except keeping the ->set_label() text to the left and placing the pencil icon float right on the field itself, where the 3 dots are and in place of the 3 dots.

As of right now I only have this need for using the textarea field as a Custom Css field and I would like that area to initially be small, but when clicked on to load in the popup so then the user can enter their custom css.

See below the Layout Css field is where I would like to place this, instead of creating a bigger Texarea which would have to stand alone pretty much.

But in general, the popup option for all fields, not just in the Repeater or Layout fields would be nice!

Thoughts?
