@macandcheese @jcfranco should the side panels be a higher zindex than the center ones?

[driskull]

@macandcheese @ashetland I need some advice on which shell panels should be higher z-index. Should we have the side panels always appear over the inner panels? Or do we need to have some sort of CSS var or property to allow users to set z-indexing?

[macandcheese]

I'd agree that side panels should appear over inner panels by default. That said, if there's a way to allow it to be overridden with css variable or other tactic, that's a good option to provide.
