Agreed, but I think it wouldnt be controversial to keep an existing
user created layout, and you seem to agree with this sentiment.

I tried just removing the kill-buffer, but that didnt work, I guess the

and the content just replaced everything should work, but aparently not.

If you come up with a patch I will try it!
