Plugin for the Advanced Combat Tracker application.
The normal duration field calculates the total time in combat. For merged encounters (such as the All encounter), the duration field is only the sum of the durations of all encounters. Any time between encounters is not counted.
This plugin adds a TotalDuration field which tracks the time from start to end of the encounter. For merged encounters, this is the total time of all encounters in the merge. This can be used to track total time of a dungeon, etc.
You can install this plugin from the Plugins tab of ACT. Once installed, you will need to enable the TotalDuration field from the options menus. There is one field for the encounters view, and one for the combatants view.
