Void Incursion Tracker (VIT)

This is something I threw together because I was tired of opening my map to check the Void Incursion progress and was getting UI errors on the bar fill sometimes. I couldn't find any other mods that were doing what I wanted and were still functional.

It's a widget-style mod that shows while you're in one of the Void Assault zones and quickly gives you the current Void Incursion percentage and which zone it's in without opening the map. It'll also give you a rough estimate of when it might pop next based on how fast the zone is progressing.

Features

Always-visible progress bar - shows the current Void Incursion percentage in real time, updated automatically.
Follows the assault around the region - the assault rotates through the Quel'Thalas zones (Eversong, Zul'Aman, etc), and the tracker picks up the active one on its own.
Live event handling - when the Incursion actually fires and you're in the assaulted zone, the bar turns orange, reads EVENT ACTIVE (or UP on the mini-circle), and shows the objective line telling you where to go. If you're somewhere else in the region, the live pin isn't sent to your client, so it shows a best-guess LIKELY ACTIVE based on the bar resetting, you will have head to the zone to confirm. I've found that when the event ends, the Incursion % is around 10%. I've cut off the 'Likely Active' from 12%+, but I have seen it end at 15% with only a few people doing. May add an option to fine tune this or keep looking for a way to poll it despite not being in the zone, but for now, it's best to pop over to whatever zone the event is in to get the most accurate data.
Minimize to a button - collapse the bar down to a small round icon showing just the percentage, then click to expand it again for more info.
Rough ETA estimate - watches the fill rate and estimates how long until the Incursion pops. This varies in real time based on how many people are running Void Strikes.
Sound alerts - get a heads-up when progress crosses a threshold you set, and again when the Incursion goes live. Both optional.
Waypoint button - one click drops a map pin and super-tracks the current Void Strike (or the Incursion itself when it's live), so you know where to go.
Options panel - set it up under Options → AddOns, or with /vi config: lock, scale, transparency, custom bar colors for building vs. live, the alert threshold, and where the tracker shows.
Scope choice - show it in both Eversong & Zul'Aman, or only within the zone under assault that week.
Fully movable - drag it anywhere, lock it in place, scale it, and set its transparency.

Notes

Void Incursion Tracker only reads public map and widget information that the game already exposes. It doesn't automate anything or touch anything else.
