i need some help with setting up the modeling view

here are some screens i took of my current setup.
i guess my question is -

is there a way to make it so my EDIT MODE view is subsurfed like the picture? that way I know exactly what it’s going to look like as i edit? after a while the hard lines and sharp NON-Subsurfed geometry of the vertices gets in the way if what’s being modeled. the pictures should explain more.

picture #1 is what i have in EDIT MODE. #2 is what i’d like it to look like while in EDIT MODE so i can have a bit more control of what i’m doing. is this at all possible? it’s been about 4 years since i last used blender.


If you check the highlighted square, you’ll get the effect you want.

thank you so much, that was exactly what i was looking for.
