21:9 Shortcut

Hi everyone
I recently got a new Ultrawide display, and I couldn’t be happier. Well, I could, if my Kodi was able to support the 21:9 aspect ratio.
So I came to find out if there was a way to do this, and no surprise you have that covered with some great ultra wide skins. thanks for that!
I do have a question, I don’t only use my kodi on my desktop, I also use it on a media center connected to a projector in the living room.
Now, my question is: will these ultrawide skins look good there? or should I change skins every time I change location?
Is there a command that I can add to my Kodi shortcut to change skins automatically (for example, having two different shortcuts, one with a 16:9 skin and the other with a 21:9)
thanks for your help.
