"URL" or "Browser" widget is a nasty hack, makes pages that contain it almost impossible to edit
I added an HTML widget to a screen of my prototype. I'm kind of wishing I hadn't.
Although it has the "eyeball" icon in the outline, it is totally non-functional — the selection rectangle and resize handles go away, but the content remains in front of everything on the screen, making the content behind it inaccessible.
In the canvas, it only shows a small portion (about 150px, vertically) of the page is selected by the URL. This makes it difficult to gauge how the page will look while editing.
It forces itself to be the top-most layer of the page, no matter where you put it in the outline. It is impossible to have components in front of it.
It is called "URL" in the widget panel, but "Browser" when added to the canvas — this suggests that it was implemented very carelessly — you didn't even bother to name it correctly.
I'm sure that there are others, but those three are bad enough. Is there any hope that it will be improved?
