In THIS question you guys answered how I can best locate/manage probes, but I forgot to ask about observers. So I am making a new question since the last one was already answered.
Normally when I make a bunch of observers I can put them into a hot-key so that I don't lose them.
But there are times that I forget to assign a hot-key, and I also set the observer to follow one of my units.
While i'm busy with something else at another part of the map, the unit i made the observer follow may have gotten killed in action, leaving the observer wandering around.
Later, I get into a stiuation that I really need an observer, pronto, knowing that I have some scattered around the map.
Is there a way I can manage observers so that I can locate them quickly when needed? Because right now i'm left scrolling around the map looking for one that I can use.
