I went to a local PBI session hosted by Microsoft and I mentioned this same problem to the Project Manager (Msft Representative). He laughed it off as if this wasn't even worth discussing about! Let me give you a bit of a context: I come from a core DW/BI background with more than a decade architecting and implementing Business Intelligence and reporting solutions using SharePoint to custom .Net to SSRS/PBI/Tableau. Every single company I have worked with has been (coincidently) a Microsoft shop. We even provided BI services for Microsoft itself! I was on the team of vendor service providers that dogfooded SQL Server 2005 back when it was just a codename (Yukon). All of this is to convey that people like myself who work with customers out there leveraging Microsoft's BI toolset know a thing or two about what the actual users want. As trivial as it may sound, the aesthetics of a BI solution matter when our company delivers such rich dashboards to their external clients (Quarterly Performance reports in finance/investment management industry). And the disregard from that rep about on-field customer feedback was very unpleasant. Now that I see others reporting this issue as well, I'm joining their voices again and ask PBI team to please consider this as a priority item to at least take under consideration. There is a reason companies are willing to make investments into very expensive competing tools and professional looking aesthetics is an emerging theme among the userbase I have worked with thus far. Upvoted this already!
