Blender 3.4 cutting out functions?

So I’ve moved to 3.4 from 3.2 and i cant find in the uv menu pack to area button and im not quite sure why but im aware that 3.3 and 3.4 changed some uvs systems this function was helpful and im wondering why it was cut out if anyone here would be kind to explain to me why it was removed i would be thankful.
In addition to that 3.4 knife tool became bit less responsive and tends to lag when used while other overlays even line knife tool from the inbuilt addon works perfectly fine this didn’t happen to me under 3.2 and even 3.4 alpha.
