When I am designing dashboards for our fundraisers, I am hindered by the lack of ability to use different font sizes or colors within the same text box or even start text on a new line within the same text box. I would also like to add outer borders or overall color shading to individual insights within a very crowded dashboard. This would allow the end user easily to differentiate between multiple insights. Since you already offer the capability to use custom colors to show lines, columns, and charts within a custom insight, it seems logical that this capability should be added to enhance the visual appeal of the overall dashboard.

Also, if you only change one thing about the aesthetic, PLEASE make the outer borders of custom insights visible to the user, NOT just the person creating the insights!
