thats what i said or simply when using Exp Candy on a pokemon a message will ask us "how many choosen Exp Candy we would use on it ! " sorry 4 my bad English
i suggest to add a history option in pro dashboard menu for any trade or lended item/ mones, rare/ shiny encounter & released, digspot encounters, sold / bought items mones ... money transfer ... subway pass consumed money ... etc
like that player will be aware of any action held when giving access to any other player for a service
it's a pain to use many Exp Candy on a pokemon espacialy the XS Exp Candy (100 Exp points) that's why i suggest to add a NPC which can change the EXP CANDY to different size (L/M/XL ...) or simply when using Exp Candy on a pokemon a message will ask us "how many choosen Exp Candy we would use on it ! " .
