Mix associated revisions with journal entries
when an issue has a number of associated revisions and comments it becomes hard to figure out the order in which things happened. If the revisions would be interspersed with the other updates/journals, the sequences of events becomes obvious. On long discussion threads like they happen on open source projects, the associated revisions are out of view from the comment form, so people might not notice that a certain issue had been fixed already.
At the moment in the default theme, the block of associated revisions is floated into the comment area, so its with is reduced by half which can get quite ugly (and potentially hide content, think long preformatted lines). This issue would also be fixed by having one integrated view.
If this finds approval I'm quite willing to provide a patch
