The 'design preview' window is set to always be the topmost / frontmost window when running XD. This is a problem because it deviates from standard window behavior on a mac.

If a program has multiple windows that I can minimize or dismiss, then I should be able to bring any window to the forefront by simply selecting it. All other windows should then automatically stay open but appear behind the topmost window.

I just want XD to follow standard practice on the mac. I'm very comfortable switching between windows using cmd+~ or using the 'window' menu in the toolbar.

I would prefer to keep the preview window open all the time and move it behind the workspace window rather than closing it and reopening repeatedly.

Also, I work on a large 27" display, but space is still a limiting factor when trying to prototype and preview a desktop design.

I'm guessing the developers thought this would be a nice feature, and perhaps it is when designing a mobile app, but when designing a desktop app the preview window takes up too much screen real estate.
