Hi, I'm quite suprised how much the Qt dialogs differ from the Xform ones. I don't mean the way they look, but their contents. Some Qt dialogs have a totally different layout and arrangement of items.
This should be avoided. Explaining how to use LyX will be unnecessarily complicated: if you use Xforms, do blablabla, however, in Qt you should do..... This UI layout definitely needs to be equalized eventually! Rob.
