Err... No, sorry, a bug tracker for the Cool SL Viewer is not in the pipeline for now... It would take too much work and time to setup and maintain, and won't really be worth it since existing bugs in the Cool SL Viewer are 99% of the time bugs existing in the official viewer (and thus referenced on the official
JIRA).
Plus, I'm usually pretty fast at fixing bugs related with the Cool SL Viewer patches (or to remove the offending patch when I have not enough time to fix the bug).
