About brievety. I think it's a misunderstanding. It's not about being short to be short, or look nicer. I don't really care about one or two chars more or less. The point is that the palette label should be small enough to remember and descriptive enough. It should also be easy to spot in the list. In the case of "Frames & Measures", the majority being frames, I would not sacrify brievety to exhaustivity. I don't think it's misleading because it's not a perfect description of the content. Frames is short and easy to remember.

Of course, I agree, by default, the palette and master palette should use the same entries. For the Basic palette, it's less mandatory.
