Checkbox: "Display sentences with the new design"

[alanfgh]

The settings contain an item with the caption "Display sentences with the new design. Note that you will not have all the features from the old design." This is hopelessly vague. What is "the new design"? How new is it? Which features are new? Which features are missing? And in the absence of any of this information, why would anyone (except for the extremely curious) click this box?

I understand that it may not be possible to cram much more information than this into the caption itself, but it should at least link to a wiki page that lists the new features that are enabled with this choice, and the old ones that are not supported.

As for the other features in the "Experimental options" section, they seem to have been around for quite a while, maybe a year or more. If we're not aware of any problems with, say, the "Display button to copy a sentence to the clipboard" option by this point, then we should take it out of the "Experimental options" section. And I'm not sure the full "scare text" is required: "Options in this category are not fully functional, may not work for everyone and/or are in a phase of beta testing. They may change or be removed in the future." Isn't it true that any element of the interface could change or be removed in the future?
