I really like the "open floor plan" of your pin and sweeps area. I am starting to think about converting to that style...I am seeing less need for the higher benchtop lately...hard on my shoulders i think...
I had seem something similar on YouTube...Lance Johnson's set up...but your's is way more custom made, organized, and tidy!
Lance has a wider version of your open drawer style and has a bunch of things mounted on a (metal) wall in front of him...his third hand, GRS bench pin, GRS benchmate...a soldering board with a dovetail mount for the GRS...
he just flips the third hand out of the way when not in use! It's a unique way of working!
...water, pickle right in the drawer, with a soldering brick...he does kinda just toss everything in there though...definitely not tidy, but interesting!
