This is nice. Note, however, this interesting bug:
- open user guide - right click on TOC inset to open Outline - right click repeatedly: note how the outline pane grows with every mouse click, and that it cannot be resized again. BTW Abdel, while you are at it, there's also still bug 4260: http://bugzilla.lyx.org/show_bug.cgi?id=4260 Jürgen
