Back to the no smoking signs, unless you get a close look at a still, they could just as easily be read as "NO SMOKING OF ANYTHING ON BRIDGE" (my emphasis).
It also brings to mind some "No Smoking" signs listed in a vendor catalog at a Star Trek convention, many decades ago. Signs like "Smokers will be sterilized" (with a picture of Nomad zapping Scotty) and "Smokers will be introduced to the Salt Vampire."
Then again there's a fairly common no smoking sign in Alaska: a picture of a puffin, a lit cigarette in its beak, with the international "No" symbol superimposed, with the caption, "No Puffin."
One bit of design I very much DISLIKE is something that showed up in the Short Trek "Q & A" (and I remember seeing it before, either in DSC or in the Abramsverse): turbolift shafts as 3-dimensional railroad tracks in large open spaces. Pressurized internal volume will likely always be at a premium on spacecraft, the supposed presence of large unfinished areas on Enterprise-D notwithstanding.
