Create a centralized repository for user-created custom reports
It would be nice to have an 'exchange' of some sort where people, who have taken the time to create custom reports, can share them. Giving others the ability to improve and tweak them, then release them, will increase the number of custom reports significantly, and could lead to a larger array of default reports included in GnuCash.
This is a very nice idea. However, it requires some people who have a vision of an active (possibly moderated) user-community. This is not what the gnucash developer people currently can do or have in view. If anyone else wants to start such a site that collects and promotes such a feedback, the developers will happily support them, but the developers will not be able to provide such a place themselves for now. Sorry for that.
