As Sketchup did it - Enscape should also have an online library of uploaded users content: assets, materials, backgrounds, etc.
Can we suggest it? 
Thanks for your inquiry.
This is in theory a great idea of course but once it comes to managing that content it gets tricky due to copyright reasons and the extra resources required to police this system - So for now, this really isn’t something we have planned I have to say, but of course, gladly forward it to product management via our portal and feel free to discuss this further here if you like.
