Please add the ability to set global values for things like measurements and page sizes in Reporting5. It is so incredibly tedious having to set it to millimeters and A4 every single time I create a report or add a sub-report.
Templates for layout that I can plug-in my new layer/datasource to would be top of my list too. I have to set up the same corporate logos, headings, lines, cross-band boxes etc. every time rather than just having a template to start with.
