Having the ability to copy a visual (with applied highlighting) to paste into other applications would allow for reports to be written with narrative around each visual.
If pasted into a Microsoft office application it could carry the link back to the relevant report (if permissions allowed) with the filters that feed the visual, essentially a bookmark link.
Would be great if this would include all of the visual, rather than just what is displayed on screen, for example a matrix with all the rows. (Should also apply for printing)
Could wrap the picture in a power bi branded frame to improve adoption of power bi as non users be exposed to the brand.
