With these its should be quite easy to put together some nice designs

Unfortunately it seems I will have less time for playing with this now.

It's nice that a transparent bitmap is not required for that.

It is not. A label can have focus (the whole icon+text widget) but panel cannot.

It will be impossible to make both focused at once without special trickery.

I finally found utility in the screen widget. While panels should
enforce that their content is not overlapped and is nicely and orderly
aligned it should be possible to place panels or labels freely in the
screen widget so that they can be positioned over particular places of
a bitmap if desired.

I hoped it would be possible to create custom layouts in lua but it's
not necessary to use scripting in most cases and it's moved out of
grub core now. Still I would want to see some way that would allow for
creating arced panels or the like, eventually.
