If possible, it would be great to have a relevant name/string passed along when alt right-clicking to create a waypoint, e.g. /way Hallowfall 42.69 53.84 Evan and Emery. When using the addon Map Pin Enhanced to track multiple pins, it's incredibly useful to know which is which. Thanks!

Interesting, ATT doesn't currently interface with this addon as we only have custom integration designed for TomTom currently. Curious, when you plot a coordinate using ATT and this MPE addon, does it plot multiple coordinates or only one?

We could probably get a similar integration for this addon as well hopefully to support what you are asking in a similar way to how TomTom does. For instance, here's an example tooltip for a TomTom waypoint on the map.
