Redmine

When a user comments on an issue without changing any of its properties, nothing shows up on the activity timeline. If you're not subscribed to the issue, the only way I've found to keep tabs on this is to sort the issues by when it was updated. I think new notes on an issue should show up in the activity timeline even if the issue's properties haven't changed. I could probably write a patch, but it looks like it might be some work so I didn't want to go through the effort unless I knew it would be a worthwhile endeavor :) Plus, it could potentially be a new category of activity rather than being the same as Messages.
