Fairly often, we find ourselves wanting to review the final state of an entire project at the end of a long and complex development, rather than any particular revision or set of revisions. This turns out to be extraordinarily hard to do in Crucible. We've managed to simulate the behavior we're looking for using EyeQL:

select revisions from dir /path/goes/here/ where is head and not is deleted and path like *.* group by file

So, the enhancement request is: couldn't there just be a button for that behavior?
