I just want to ask if there are any plans to integrate issue support in the new squeaksource development. I don't know redmine but it looks similar to trac I'm using since a few years. I also know jira. To me one of the biggest gains of these systems is the integration of source, issues, timeline and wiki. You can easily reference a ticket from the wiki, a ticket from a commit message etc. In trac it is #<number> is interpreted as a link to a ticket. In jira it is <projectname>-<projectnumber>. In jira you can alter the issue tracker by committing new sources. If you write yourproject-58 into the commit than you can change the state of the ticket to something like "needs check" "treated" etc. It sounds a bit blurry but it helps a lot. 

Sad but true biblicello [1] wasn't in place at the right time. I think it has huge potential by leveraging pier usage.
