Related wishlist. I have a large monitor, easily large enough to support a toolbar 40-50 slots wide. I would like to be able to either expand the existing toolbar(s) to one with 40-50 slots, or alternatively display additional toolbars to the left and right of the standard game's toolbars. (I don't want to add more toolbars vertically, because that starts to encroach on the centre of the screen, which should be kept clear. This would be perfect for keeping lots of blueprints handy, and allowing me to keep all the belts, inserters, pipe, chemplants and assembly machines etc available without needing to keep opening my inventory everytime I try to manually build something.
Personally, I mostly mouse select items from the existing toolbar, so I don't care about keyboard support for the additional items. (Although I'm not suggesting that the existing support should be removed). Please make either the width (number of items horizontally) of each toolbar, or the number and location of visible toolbars, adjustable by the user either, via options or config.ini, or mods/Lua commands or additional researches.
