The existing labels, "Tools", "Allies", "Emotes" etc. sound nicely organised, but make no sense in practice. I'm going to set and forget the wheel as I move between different types of content. Thus, I want to label them with "PvP", "PvE", "House Tour", "Cyrodiil", "Trial", "Role Play" and the like.
PC EU: Magblade (PvP main), DK (PvE Tank), Sorc (PvP and PvE), Magden (PvE Healer), Magplar (PvP and PvE DD), Arcanist (PvE DD)
PC NA: Magblade (PvP and PvE every role)
