Martin,
I think we should add "Minipage" and "Parbox" to the box type lists instead of "frameless". If the user choses Minipage or Parbox, then the "has inner box" stuff should be completely disabled.
Otherwise people will bug us because they do not find minipage anymore.
The situation is worse (UI-wise): I insert a frameless box and I get a minipage => Maximum confusion!
I don't know whether we have to distinguish between minipages and parboxes or whether one of them supercharges the other. But in the UI we should not mix _frame_ properties with general _box_ properties.
IMHO the menu should look like this:
Box => No Frame Single Frame Double Frame Oval Frame, Thin Oval Frame, Thick Shadow Frame
Alternatively, we can remove the submenu and use "Single Frame" as default.
As box label, I propose to have, e.g, "Box (No Frame)". In this way we can save a couple of messages and gain a greater consistency. (Martin, I don't think that the size of the label really matters.) Or even better, we visualize the frame. I guess this can be done in a simple way technically.
