I love the addon, but from what I can tell there is no support for the rarely seen Underground option when using the Wormhole Generator: Northrend. Currently I always shift click on the portals to double check, as I found in the code that opens the default menu, but it would be really cool to be able to have the portal show up in Dalaran when the Underground option appears.

I know this is something that might be difficult to test given how rarely it shows up.

Just logged on and got the option (she had full stock too) 👍
Will be adding it to the next version with accurate coordinates, I'll even give it a star icon on the map!

Pushed new version, should be available for download soon.

Should be easy enough to add, I just need coordinates for it. I wasn't even aware of this option, and I've been using the wormhole for years.

The coordinates on the Northrend map would just be where Dalaran is.

The 6th option for Underground rarely appears, but when it does and you choose it, it sends you into the pit under the grate in the horde side of Dalaran where a vendor, Kaye Toogie, sits. It is the only way to get to her and she sells Mechanical Dragonling schematics, and she is even the only way to get the Arcanite Dragonling schematic(other than people selling it on the AH).

When I first actually tried to start aiming to get the Arcanite Dragonling schematic, I actually had the Underground option appear twice in a row. Unfortunately all 3 dragonling schematics that Kaye sells are limited in quantity and only restock once every 12 or 24 hours or so, and she will only talk to you for the first 30 minutes after teleporting in, so waiting beyond that time period for them to restock is pointless. And of course both times she had nothing to sell, and I haven't seen the option appear since.
