The whole matter of adding a new tracker is overly complex, IMHO. It wasn't until I found the FAQ entry that I realized how to do it.

The core problem is that the trackers are added at the global level, but then need to be added again at the project level. The UI for the latter portion is also rather hard to find. While I can appreciate that each project can override global settings, in this particular case, I'd expect the global setting to push through to each project and then disable on the projects which I don't want it on. I haven't come up with a case where anyone would want to do that, but I'd imagine some exist. I'd expect them to be the exception rather than the rule.

If the intention is to keep the current approach, then it'd be nice to have a list of checkboxes for each project to enable the tracker for from the tracker UI. This would save an administrator from having to go to n different projects to update their settings.
