In old PolyHitbox versions the mod itself had a keybind for toggling hitboxes, but in newer ones it instead adopts the vanilla keybind and directs the user there to change it. However, the vanilla keybind REQUIRES holding F3 to function — it isn't immediately apparent since the option just shows the binding as the single key, but it's in the "debug" setting which is seemingly hardcoded to require F3 in addition. This means it isn't possible to assign it to a single keybind (Ex. just "B") like in older versions, so the mod would benefit from returning to using it's own keybind rather than the vanilla one.
