You can open the main window from your launcher (eg norganna slidebar) or from a slash command. Right click on the list elements for the reports and exports.
Records buffs automatically (at ready check and if DBM is installad on pull/kill/wipe) and stores in an internal database. You can view the database in a window.
Should group recordings based on instance and reset time if available.
Has some scripting capabilities in settings for awarding.
Show the database window:
/slacker show
Record buffs manually:
/slacker manual
