View pokemon strengths and weakness in game

Like on smogon you can rest your mouse over the pokemon's types, like ground, for example hippowdon, It shows that it is immune to electric, resist poison, rock, weak to, ice, water, grass. I was wondering if we can have a poke dex function like resting the mouse on the type of pokemon, or in battle tab rest the mouse over the pokemon to know there strenghts and weakness other than just stealth rock, spikes etc. Sorry i don't script, know how to yet, so i can't understand how difficult it would be for you developers to do something like this. Also SORRY in advance if this was already in idea and it was thrown out and you will not do it. I reread the rules etc and i didn't see it but i do at times over look things. But I just want to say that this could help newbies/noobs who don't do pvp/even bosses as much or just starting out to rest a finger on android or mouse on computer to view the pokemon weakness or strengths. Be nice to know if a pokemon is very weak then just weak to something. I can understand if you don't want to do this. Since players could always just type it into the web browser to view this under smogon website etc. Tired, so my grammar might be bad.
