I also propose to reconsider the position of the dock. Now it's on the
right of the canvas but below the toolbars. I think it would make
sense to expand it upwards so it would be on the right of all the
toolbars and the menu bar, shortening them. The right end of the menu
bar is always wasted anyway; as for the toolbars, all of them are now
squeezable without any loss of functionality (a drop-down replaces
those items that didn't fit). Similarly, I think the dock should be on
the right of the palette at bottom - but still on top of the statusbar
as now, because it's difficult to read statusbar messages when
statusbar becomes too short. All this should give the dock a lot more
vertical space which is valuable.
