Torhal, this might be a hell of an ask, but since you have to rewrite Archy anyway, here's my two cents: incorporate the visual slices or wedges feature from Archaeology Helper, along with GatherMate2 pin support. The HUD is incredibly useful, and it doesn't look like Oscarub is returning to update the addon.
This would make Archy the ultimate Archaeology addon, with one-stop-shop features!
I am using Archy 188.8.131.52 and since the last patch (7.3) I can no longer view the archy window showing where nodes are to be and what artifacts we are working towards. Please help me! I've tried changing things but to no avail. I'm at a loss and cannot do archaeology at all at this point.
Torhal is a very busy man. He has around two dozen projects that he works on, and Archy, NPCScan, and _NPCScan_Overlay are about the most complex of the bunch.
There has been an unofficial patch posted for Archy, but it only works in English. I have helped where I could by providing the new textureIDs for the various races that have archaeology, and I updated the Wowpedia API article. But, as I said, both of these are temporary fixes until Torhal can make it work for all languages.
