Custom artboard shapes
There is only 1 corner style at present in adobeXD,when you create new artboard. In reality screens have different shapes like for example Watch screens are also circular so there should be option to adjust that.
It would be really helpful for designers to be able to change the shape of the artboard to have a notch cutout. This will make it easier to design for all the different phone screens without any hassle.

For new devices like iPhone X, Samsung S8 and many more upgrades, I think there must be rounded corners artboards with status bars elements included in artboard.
