Possibly, also a setting that allows us to set if a player can track such quest/objective (this could be useful for things like DIALOGUE objectives, but player need to find the NPC by themselves, without any help)

Also, possibly, an event that gets fired whenever a player decides to press the Track/Hide button, an one for the Abandon button

Last, but not least, an event fired when a player completes a stage/objective

Added ability to set quest tracking from the server.
PixelmonPartyStorage#getQuestData().setTracking(QuestProgress)
PixelmonPartyStorage#getQuestData().hideTracking()

Added events for quests:
AbandonQuestEvent
FinishQuestEvent (Complete, Fail)
NPCInserterEvent
QuestActionEvent
QuestObjectiveEvent (Complete, Progress)
QuestStageEvent (Complete, Set)
