I'm using TW in TiddlyDesktop (NWJS) and when I dock the window left or right (Windows Key + -> or <-) so that it takes half my screen width (1920px/2 = 960px) then only the sidebar is visible (s1.jpg).
That can't be right: surely the "river" is more important,
If I slightly widen my window to 990 then the river appears (s2.jpg).
What's the mechanism/rule here and how can I control it?
