One of the first projects I ever published was Consolid8, an add-on for World of Warcraft. It was designed to reduce the volume of low-importance messages flooding the chat window during group combat, by summarising them to the user after the event.
The add-on was featured on WoWInterface when it launched, and has since been downloaded over 3,000 times. Unfortunately, I’ve been struggling to maintain it since I stopped playing the game years ago. As usual, the source code is on GitHub.
