I installed Linux Mint the other day and I have been living in the terminal ever since...

One of several issues that stump me is the fact that I install something and then it never seems to appear anywhere. Some installations, like Zenmap, it goes where you think it would go, under "All Applications." That's a no-brainer, right? I mean, why doesn't EVERYTHING go there? In that list of ALL APPS you have GUIs, text editors like Nano, links to more software, etc. Then why on earth do I have to hunt for Gnome Control Center, for example, and there are several more I can't think of right now.

Is there a secret trick to find out where something is going to be found according to the category that the thing is?

Because the GNOME developers in their infinite wisdom

1) named it "Settings":
2) made it be shown only in GNOME:

I see, lol. Thanks, shruggy. I guess eventually I'll also shrug at the ways of this system that appears roundabout only to the uninitiated. I'm sure I'll get used to looking in all the right places eventually...

If gnome irritates you, just install a different desktop.
