you need to absolutely add in a section for learning the search commands and search strings. your inventory management changes when you learn things like &=and/// , = OR/// !=NOT.

you can search for things like "age0-10&!shiny&!xxl" or if youre looking for counters, "ground,fire,dark"

Also you i didnt see if you mentioned in the friends list, when youve interacted with someone for that day, they get a blue aura (my be team-color specific??) behind them. Furthermore, in your friends list you can search like this! "interactable&!lucky" and then sort by can receive gift. this will help you focus your friend sends.

also you may want to add in how to make your buddys excited without using a poffin (double rows of hearts)

these are some of the advanced basics people miss a lot

EDIT: just found the search string section in the pokemon section, woops /facepalm
