BriefQuestComplete is a small and simple addon created to reduce the amount of system message lines shown when completing a quest to a single line that links to more information if wanted.
When a completed quest has rewards, those rewards will appear as a chat link that will display a tooltip containing all of the item, money and experience rewards for the completed quest. Any items in this tooltip can be clicked to open up a seperate tooltip for that specific item.
When a quest was a daily quest, the single line will display the amount of dailies completed or select the option to show the amount remaining for the current day.
Use /bqc chat command to access the options window or find it in the list of addons in the blizzard interface options, addons section.
The functionality of the addon should work for all locales.
