Since we are having crossplay and therefore a Bungie-Name Friendlist ingame, it would be pretty helpful to give players in your friend list notes, similar to how World of Warcraft and other MMOs offer that. Then I could, for example, give players notes like "VoD Raid LFG" or "PvP Guide I met" and such things. Of course on console it would be a bit time-consuming to give players notes via controller input (unless you can use Keyboard for it too) but in the end it would be something helpful to the players.
