This plugin counts the number of Marks of Grace that spawn while you're doing rooftop agility.

The plugin provides the following metrics:

• The total number of spawns.
• The current number of Marks on the ground
  • Useful for the Ardougne course.
• The time passed since the last spawn.
• The estimated amount of Mark spawns per hour.
  • Appears after getting at least 2 spawns.

• The plugin tries to remember where you dropped marks and ignores those tiles when detecting mark spawns, so dropping your marks on tiles where they can spawn will lead to issues.
• The plugin assumes you always eventually pick up the Marks before they despawn. If a mark despawns while you're not there to see it, the "Marks on Ground" counter will get desynced.
  • Pick up any Marks in the area and select the Reset Ground Counter option on the overlay shift-click to fix this.
  • Alternatively shift-click the overlay and select the Clear option to reset everything.
