This is on in our plans for Power BI Desktop! Stay tuned :-)
This month we added the ability to format text fields based off a numeric field: https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-may-2018-feature-summary/#conditionalFormatting
We also are planning on adding a feature that will let you format your text based on comparisons. I’ll update this idea based on our progress on that feature.
Thank you all for the feedback since our last update. We’re working on building a new navigation experience to allow authors to customize a folder-like structure for all the contents within Power BI Apps. Stay tuned!
Thanks for the feedback! While this isn’t (yet!) on our near term roadmap, please keep voting and giving us feedback on the idea. We definitely see the need and will update the idea when we are closer to adding this feature.
