I have on just a few occasions wished for the ability to stop the clock entirely so that I can examine the geoscape without time passing. A geoscape "Pause" button that still leaves me with the list of geoscape options but without craft still creeping along or terror sites expiring. The clock stops when I'm looking at a base or ufopedia or whatnot, but why not when I'm looking at the globe? There's no room for a new button without rearranging the interface but what if you clicked the currently selected time button again, which would then DE-select it and maybe say, "Game Paused" somewhere on screen.
