haha yeah.
I am annoyed whenever I reach a chest and it's just 50 rupees but I'm glad you have to put it back when you're maxed out. If ever you need cash you can always visit a dungeon and fill your pockets.
Also I like the bug collecting, but only because if you visit Agitha when you have bugs but tell her you don't and leave, she stops you at the door and says 'I know you have bugs!' just before you leave (the first time anyway)... it was kind of creepy.
