Album view: resizing window below apparent minimum width does not reflow view and prevents window resize drag point
Not sure if this known already. In the album view, when you resize the window to the minimum horizontal width, I'd expect the four-albums-column to reflow to three-albums one. Instead, the fourth column gets hidden (no horizontal scrollbar visible). Hovering over the right-hand side of the window will not show a resize-horizontally mouse pointer. You have to resize the window from another drag point.
