[Enhancement]
It's always been really stressful to me how, as soon as an enemy drops some rupees, hearts, bombs, etc. you better drop what you are doing and rush over to pick them up before the EVAPORATE. this was probably done for RAM limitations or something back in the day, but is totally unneeded now I'd bet.

A slider in the debug menu to make things stay a specific amount of time, or a multiplier, or just a toggle that makes them stay until you leave that map zone, would be great for reducing the pointless stress caused by making items appear in the world.
