Save for web
Why don't you implement a "save for web feature" like in illustrator or photoshop? It would be very useful to export assets for web starting from layout designed in Indesign.
Would love this! We almost always build our web assets in indesign because A) we are usually adapting them from pre-existing print campaigns built in InDesign and B) For 90% of the designs we create, InDesign is just an easier tool to use than Illustrator or Photoshop. But when it comes to exporting, right now we're stuck with the very limited JPG/PNG export settings, which yield larger than necessary files sizes, or we have to export at high-quality and then web-optimize them later with a different program. Would be much easier if a true save-for-web was built-in.
