Thanks for your input, everyone.
Our thoughts:
1) We are not big fans of making radical changes to this area of the system because:
a) It's a very big job
b) No matter what we do there will be people who are unhappy. We do not want to compete with professional report writing tools like Crystal Reports and Aware IM will never be as good as them anyway
2) Despite some shortcomings most people seem to get by OK - it may not have all the bells and whistles, and sometimes it takes a while to develop a report, but the end result is still there most of the time
3) Version 5.9 includes a feature that addresses one of the shortcomings of the report writer - it allows users to save their ONLINE CHARTS as images, which can then be used in a report.
4) We have seen many threads about different shortcomings of the Report Designer, but we couldn't see anything CRITICAL there. So, if you have a missing feature that is CRITICAL, please describe it here.
