As someone who loves farming up patterns, it'd be great to see those patterns on the map so I knew exactly what all I had to go after in each zone.

Maybe just start with the items that are sold by vendors? You could leverage Questie data for mob / vendor locations in Classic. (=

It'd be cool to just show a colored profession icon on the map to indicate a missing pattern / recipe / schematic / formula / etc. (Overlay a color so it doesn't conflict with trainer icons.)

A lot of data already has coordinates applies to it which you should be able to see in tooltips for the Things in the list.

Alt-Right Click will attempt to plot waypoints (via TomTom if installed) to everything nested under the group you've clicked. So when zoning into a new zone, simply Alt-Right Click the 'Vendors' header and just go to each waypoint and see what is available to buy at that time.

We don't do our own map-integration/waypoint logic at this time since it's far-better handled from TomTom right now.

... Oh are you reporting something concerning ATT Classic? Probably disregard everything I've said if so and I can move this issue to the proper repo :)

Going to close this since it's Classic-specific and Retail ATT handles the plotting of coordinates as expected for Vendors which have unlearned recipes.
