Looks like you've been busy! One quick and obvious question: how did KLyX do all this? One other quick and ignorant question: can you embed the existing xforms WorkArea widget in a qt2 one. Simply to get a qt2-ified LyX main window. GUII-fying properly the minibuffer, menubar, toolbar, (drop down), a mechanism to create multiple WorkAreas in one LyXView; all these are orthoganol to the WorkArea stuff you describe and it'd be nice if we could move gradually to the best solutions. Incidentally, I think task 11 should be task 1 but that's going to happen sooner rather than later anyway! Angus
