This sounds very promising!!!
I won't be able to test anything as I am without access to my pc for a couple of weeks, but I really hope this makes starting game transitions more seamless (both from emulators and Steam), but most importantly for me, as this has been bugging me for years, finally fix the transition when exiting a game from Pause screen, where for now it goes back to gameplay for a split second before bringing up the shutdown theme, which is very annoying...for me at least
