Here's a link to the addon:
Now, I need this addon - but I am not smart enough to learn how to fix it myself, would be sweet if someone good at programming addons could take over the project, as the author AcidWeb asks in the comment section:
"If any EXPERIENCED addon author want to takeover this project - contact me." - AcidWeb
Here are some screenshots that show what the addon does:
1st pic you see a list of games, kinda self-explanatory, shows date/map/win or lose/rating+-/mmr/comp/length/
In the 2nd pic, you can see how it looks when you shift-mouseover any of the games on the list, you see player names and stuff. I went ahead and covered the names just in case.
I don't know anyone that has the capabilities to fix this addon, so if any of you do - please, this addon owns and I haven't been able to find a replacement.
edit: i'm pretty sure atrox arena viewer takes too much memory if i want to store 5000+ games. and it isn't as detailed.
