Well, i had a thought. Since Archaeology is a pretty popular new edition to the game, it has it's annoyances (being sent in circles when the fragment is next to you is one) Which can be countered by a little simple trigonometry (getting 2 points on green and lining it up to complete the triangle)
Is anyone aware of an addon in existance or in the process of being made, or is willing to make an addon that marks the position and direction of the previous survey, and the current position and direction of the most recent survey, and draws a "virtual" line in the game to line up the triangle, making it so you don't have to mentally mark a "line" where you're surveying.
I know this exact thing may not be completely possible (because of AVR-E ruining addons drawing in the game) But i'm aware of some addons still capable of interacting with the game world with graphics.
