Thanks for the positive feedback, glad you liked it! 
We’ve actually seen an interesting use case firsthand from a Core Booster user who highlighted the need for image choices. They’re running Gravity PDF and Nested Forms to generate complex Risk Assessment PDF docs. Nested Forms is great because it lets them put multiple risks or jobs into just one report. Now that we’ve added image choices, they can display a picture of the exact safety sign that goes with each specific risk, in the same report.
I’m sure there are tons of other cool uses we haven’t thought of yet! Nested Forms and Gravity PDF is such a nice tandem overall. There will always seem to be a good fit somewhere.
