avv recently suggested being able to buy drugs in user-specified quantities. Same thing should be in the Fix-Boy; we should be able to click on an item to craft and then specify how many and click Fix and sit back and wait. It would still take the same amount of time (i guess) so it's not like i'm suggesting any shortcut at all. This is actually a health issue...
When you focus your eyes on a point, your optic muscles work to move your eyeball. When you focus on two places back and forth over and over (hundreds of times!), it puts a strain on that muscle. But the current Fix-Boy is one step worse: we move our eyes in a deadly triangle, clockwise around and around and around hundreds (thousands!) of times when crafting. We focus on the item, then to FIX, then to DONE, over and over rapidly. This is bad, guys!
So here's a way to notice this problem more obviously: go craft 1000 rounds of 10mm ammo as fast as you can with no regard to the strain on your optic muscles. Then stop and immediately focus your eyes on those same three places but go backwards! I mean go counter-clockwise for a minute from DONE to FIX to ITEM and back to DONE over and over. If you notice that makes your eyes feel "weird", well...that's how it feels when you agree with me lol.
An analogy might be when you're in the yard and you stretch out a long garden hose (or extension cord) and start twirling it. That twists the hose up. Imagine that is the same effect using the current Fix-Boy has on your optic nerve. The nerve doesn't twist as much as the garden hose (it's shorter), but focusing rapidly in a clockwise circle hundreds of times has that same effect (and if your optic nerve was long enough, it might twist around a few times).
