Sometimes the floor level is a few inches off and I want to fix it, but
it's a pain to redraw the entire boundary just for that. Would be nice
to be able to adjust only the floor level. Rift already has this feature
I believe.
I personally think this would be really disorienting. It's annoying that
some apps can't be used in bed but when the horizon isn't horizontal it
tends to lead to discomfort.
A consistent default brightness is nice for app developers since they
can generally control the experience people get, but some people have
sensitive eyes or eye injuries and can't handle the default brightness.
It also exacerbates flicker for people...
