Report Theming

Hi v-yiruan-msft,

Yes, I have experience of PBIT in Desktop and the associated JSON theme files. Things seem to be moving quite quickly regards the Fabric/Power BI service and I see there are now the following file types:

 - PBIP - Project file

 - PBIR - Report File

 - TMDL format (Or TLDR as we keep calling it!) (And not to be confused with TMSL!)

The PBIT format has always had some disappointing limitations in terms of being tied to desktop. From what we've seen of Fabric, the impetus from MS seems to be to move towards doing everything in the service so seems like a good opportunity to give developers some proper tooling for effective report theming that can be properly source controlled and distributed between teams as per the file types above.

It's all quite new and limited documentation (Particularly for PBIR) so keen to find out more as we are wanting to consolidate our report theming if possible and would be nice to have a way to do this without having to share static PBIT files in the clunky way available in the past!

Cheers,

Luke
