'Make default grid once, use it everywhere'
If you copy an Artboard from a file and paste it in another file, the custom grid settings come with it. You can then click "Make Default" to update defaults for the new doc.

The ability to make a custom grid a default choice within xd. To have the ability to use that custom "default" grid on it on any new project you make without having to rebuild a custom grid for every new project.
Ability to choose a custom grid and set it to your "default" program-wide.
For instance, making your own custom grid for bootstrap within xd and being able to set it as your default would be very useful to anyone trying to make a bootstrap build their end goal for their prototype website.
