with Unity 2019.3 a really interesting Editor setting was introduced. If you go to ProjectSettings/Editor you'll find at the bottom something called "Enter Play Mode Settings",
if you tick the "Enter Play Mode Options (Experimental)" bool and don't check "Reload Domain" and "Reload Scene" Unity well...won't reload the domain/scene upon hitting the Play-Button, which means you're starting the game In-Editor almost instantly.
Now, it took me about an hour realizing this was an issue in my project because my ArticyRef objects which were set through the Inspector were always null when the game was running and I couldn't figure out why until I reverted those settings back to "default". But apparently Articy needs to at least that Unity reloads the Domain to work properly.
It's a real time booster to be able to instantly go into Play Mode and not wait several seconds. As of now it's taking me ~7 seconds to load the game with default settings. And this in an empty scene. It'll only take more time as soon the scenes scale.
Sooo~~~~ is there any chance you'll support this settings, too?
