A simple addon that lets Blizzard's native map pins, added back in Shadowlands, work with typical internet /way commands. Basically, it's TomTom for Blizzard waypoints. 

Features:

• Supports any typical /way command you'll find online
• Outputs the waypoint description to chat, so you don't forget
• Allows you to paste in a saveable, scalable, sortable list of /way commands (or coordinates)

Usage:

Single Waypoints

• /way x y
• /way x,y
• /way (x,y)
• /way x y Description Text
• /way ZoneID x y
• /way #ZoneID x y
• /way Zone Name x y
  • Tries its best if multiple matches are found
• /way here, me
• /way clear, c
• /way options, o
• /way help

Waypoint Lists (/way list, /way l)

Blizzard waypoints DO NOT SUPPORT more than one waypoint at once.

• Opens a new window for you to paste in a list of /way commands (like from WoWHead comments)
• Creates a moveable, minimizable, sortable window with your list of waypoints.

  • [<] - Copy the current list back to the input frame
  • [+]/[-] - Maximize or minimize the window to just show the last set waypoint
  • [Opt] - Opens the options panel

  • Save List? - Saves the list when closed/logging out
  • [Clear Current] - Clears your current waypoint

  • [Closest] - Sorts by the closests point to you
  • [X] - Sorts by X coordinate, toggles ascending/descending
  • [Y] - Sorts by Y coordinate, toggles ascending/descending 
• Waypoint Buttons
  • [X] - Remove this waypoint from this list
  • [Set] - Set your waypoint to this
  • [Next] - Set + X, sets your waypoint to this and removes it from the list
