When using multiple desktop panels in different edges of the screen, they get on top of each other, which makes using them very inconvenient. Would be nice if there could be an extra option to set a panel in such a way that other panels would not cover the same space, e.g. if there's one at the bottom/top, then adding another one to the left/right should have the option of being shrunk so as not to intersect with the one that's already at the other edge.
I'm not having a z order to panels. They shouldn't be stacked, the fact that they can is a bug and there's an open bug report on that
