I am redoing this cabinet to house my tv. I’m painting it white and 2 of the doors will bifold and slide into the cabinet out of the way on one side. here is the cabinet before I painted it. My question is, should I put a knob on the cabinet that does not open on it’s own or just the 2 that open? One door will open to the left, and the other 2 doors to the right. This will be In my family room and the knobs at the top corners.

I plan to use glass knobs.
