Small UI tool to help players record positions for quest objectives.

Problem: Players need to be able to easily remember in-game locations so they can use them in their quests.

Acceptance Criteria (AC): What does this tool need to be able to do?

Mockup diagram

Must Have:

• Show a player their current zone, subzone, and coordinates - collectively, the player's "location".
• Save a location with a descriptive name. (globally, across all characters on a bnet account)
• View a saved location while they're writing a quest.

Nice to Have (actions to support the primary objectives):

• View a list of saved locations.
• Update existing saved locations. (overwrite with current location)
• Edit existing saved locations. (manual modification)
• Delete an existing saved location.
• Delete all saved locations.
