GZDoom 4.11.0 released ^^True, that is a regression that I haven't noticed. It's supposed to immediately execute the command you typed. Will fix.
I'll think about on screen buttons. You can go to Options -> Go to console to open the console for now.
Renderer changes require a restart in general. I think it even shows a tiny message saying that when you change them, though it is pretty hard to notice.
