Hi Tom,
Thanks for reaching out and for your kind words.
I will give my best to answer your questions.
Regarding the reports, please see here the PDF example of the default report. However, the Client Reports extension provides you the ability to customize reports. This means that with basics HTML/CSS knowledge you can fully customize reports to reflect your brand.
Regarding your suggestions for the Branding extension, please feel free to post Feature Suggestions to the Features section so other users can support your ideas and vote it up.
Regarding the official roadmaps, this is a difficult question. We do have plans, but plans always change 
Basically, we are always focused on our users needs, but when it comes to final decision what to develop next, I believe that Dennis, MainWP Co-flounder explained it best in this post.
Let me know if there is anything else I can help you with.
