Is there a Galaxy overlay keyboard shortcut, that would display Galaxy UI and friends list? Similar to the way SHIFT + TAB opens the overlay in Steam.

not in the current version

They say (Soon) but I say how soon? :)

Soon™.
(Maybe before the year's out, if you're lucky. =) )

Ah, I see you have yet to learn. Soon is actually a very specific time distance from now, but one that cannot be measured using the common concepts of seconds, hours, months, decades, millennia, and simple parts thereof. It is probably easiest to think of soon as related to the common concept of time in the same way as imaginary numbers are related to the real number scale (that's not actually true, but it's a simple enough explanation).

You mean GOG Soon™ as GOG has it's own very liberal idea of Soon™. ;-p

They just have a great model: "When it's done."

Hence the "™". "Soon" normally means "within a reasonably short amount of time" (depends on context, but generally minutes/hours/days/weeks); GOG's "Soon" means "sometime before the next Age of Man, but not necessarily in any time frame measurable by man". You know, Soon™. ;D

That's one way of putting it. XD

I hope when they add it, to be like the one in Origin, because it's way better than the one in Steam. How do you think ?

Well, if they intend to compete with Valve...
