Hm? The bugtracker for the Pandora is pretty simple, compared to most other bugtrackers I've seen.
What was too complicated for you with it?
I can't imagine a usable bugtracker to be a lot more simpler.
About having a bugtracker included into the boards:
I'm all for that. Same for Wiki, same for the repo. The boards offers a login API, but I'd need some coder who could change the wiki, bugtracker and repo software so it uses the logins from the boards.
Any good web developer here who wants to do that?
