# Objective The `SetInputFocus` trait is not very useful: we're just setting a resource's value. This is a very common and simple pattern, so we should expose it directly to users rather than creating confusing indirection. ## Solution Remove the `SetInputFocus` trait and migrate existing uses to just modify the `InputFocus` resource. The helper methods on that type make this nicer than before :) P.S. This is non-breaking as bevy_input_focus has not yet shipped. ## Testing Code compiles! CI will check the existing unit tests.
