Crossbow Expert lets you make Ranged attacks (regardless of what you use to make such an attack; be it weapon or spell) in melee range without disadvantage. Note: you can make ranged attacks in melee range without the feat as well, it just has disadvantage, so BobTheWizard was slightly erroneous in this regard.
Anyway, wasn't this the idea all along, using your bow and only the bow as your weapon? Judo Chopping or otherwise punching with the hand holding the bow is a different "weapon". Also, the damage type is different (piercing vs. bludgeoning).
