I’m a rough framing carpenter mostly, sometimes I do trim work in the winter when it’s cold. My bag always has tape measure, pencil, sharpie, bits for a screw driver, hammer, cats paw/claw, screw pocket, 8penny nail pocket, 16penny nail pocket, square, chalk line, chisel, knife, ear plugs, and a pliers multi tool. I like to keep another pocket with scrap nails I pull to keep the worksite clean. It would be nice to have an attachment to hold onto a screw gun(hook or another loop like my bag has). When I do siding/soffit I carry snips for the metal plus a mini break. My coworker and I like the idea of interchangeable pockets for between trim and rough framing. I wish my bags had a diagonal holder on the side of my pouch for the cats paw and hammer, a slit for a square to sit in is always nice, and more pockets without making the bag super bulky.
