The treasure/bug system, outside of the redundant notifications, is something that definitely needs to stay in LoZ forever more. It is just so great, and although I wish we had more diversity as far as what we can and cannot upgrade, I believe SS pulled it off rather well. Well, honestly I would axe the bugs almost as a whole and expand upon treasures. Put THOSE in treasure chests alongside Pieces of Heart, rupees and your standard refill. Put more kinds of treasures (iron ore, coal, golden feathers, etc.) and you have a great treasure system. The whole bug thing, I get how it is executed and it makes sense...but I felt something was a little off waving that bug net around.
