custom reports based on query
Once you can view a query result (say "all open features", which is query ID=2), you should be able to see the query fields and further customize the result (like is possible in Trac) so that you don't have to create new reports from scratch.

+1. This will be definitely be an excellent feature to Redmine. I have to report to several managers in different ways and right now i have to do it taking data directly from the redmine database. It would be very helpful to build the reports inside of it.
