I would enjoy if items that gave buffs had the ability to stack the buff. For instance - drinking 2 pungent sunrises meant 3 minutes of small enlightenment, and taking 7 pouches of no-no powder was equivalent to the amount of time taking 7 consecutively would give you. Of course those are just examples, I would like to see it spread around all buff-inducing items.
I dont think its too much to ask.
