The hangar was a lovely feature in 2020 and I impressed my colleagues at work with screenshots from it.
Also it was very practical for livery painting. I used to update the livery while MSFS2020 was open, switch the aircraft to another one, and then back to it and the livery updates. I could inspect it and do more photoshop tweaks etc. It was much more practical this way than loading a whole flight to see if the livery looks Ok.
I have to admit that it was a sad thing to see it gone. I wonder what was the reason.
I hope it will be back.
Cheers
