hi;

this is more of a question for gtk-app-devel-list than for
gtk-devel-list. nevertheless…

there's no real need to "inject" a second transition. since you're
already using a GtkStack, you can use an unnamed page holding the
GtkSpinner, and show it by default while loading the other pages in
the background.

alternatively, you can place the whole sidebar + stack into another
stack, and have a separate page with the spinner inside that.

ciao,
 Emmanuele.
