Dear internet,
Fitts’ Law is not the kind of law you can break. It does not say “put things near screen edges”. It says “the bigger an object is in the direction of mouse travel, the easier the object is to hit”. What you think is Fitts’ Law is an fact a corollary of Fitts’ actual Law: since the cursor stops at a screen edge, an object at that edge essentially has infinite size in that direction.
