Hey Ryan! Definitely something I’ve been looking for as well!
I can safely say this is a feature we’d all like to see in XD.Prem Prakash supported this idea ·Prem Prakash commented
I want the ability to hide all the sidebars when I am working on an artboard. Just as you can side the Layers and Assets sidebars, I want to be able to hide the Properties (right hand) sidebar too.
