How minecrafters manage items

Hello there fellow minecrafter! I am a curious person and as such I am wondering what is your usual (most common) set up for items in your hot bar and item inventory . There are some additional questions regarding items and the way you play that will hopefully help me make interesting analysis of how players manage their items. (All questions require answers.) Thank you for your answers, Ponnywithhiccups
