My belt set up, just to add to your thinking…
Unger padded belt (awesome belt!) with L-R:
Added bull ring for my working cloth;
Bottle (just a pump bottle) for indoor use;
Unger spray bottle
Some cloths ( there are 5 straps to attach things onto the belt);
Small brush for dimpled windows, sill brush;
BOAB;
Leather pouch for scraper;
Leather pouch for small scourer pad and a small tool for cleaning out interior water channels)
Hope that helps. Obviously everyone has their own preferences with tools and the like, once you have it set up tho your muscle memory gets or put away everything as you need it.
