It makes sense to add functionality to Unreal Engine which would (IF ENABLED, so it have to be switchable functionality ON and OFF) prevent to open second instance of the Editor (Similar to many programs out-there)

Many software does utilize this functionality by the way you open it.
Example. 3DS max by clicking on the Icon will not start second instance, except if you click with right mouse button and open a new instance
(3DS Max 2017)
Photoshop does the same. (Second instance can be opened if you click on the icon on the toolbar, otherwise it just minimizes or maximizes already opened window)

…After mentioning this… i have tested many software i got here and i found that almost any of those support this functionality,
except Unreal Engine Editor and of course some Computer Games, But Maya, 3DsMax and many other professional software support it. So its pretty standard already.

The problem with Unreal Engine IS ITS LACK OF FUNCTIONALITY in just about EVERYTHING, the instablity of the Blueprint system which gets buggy at times… Errror messages that only engine technicians can understand, Can Crash also without any warning, has no crash prevention… No safety net to prevent crashes.
Engine does not always know what the error is and says Érror Unknown… The list goes on.
