Please let us know how you would like XD’s existing Grid snapping feature to be different.
Or if you’re having trouble just finding the Grid feature in XD, please let us know where you’d expect to find it in the UI.
I cannot find anything about grids or guides, even through 'Help' in menu bar. I would look for these under 'View' as in Ai or Ps. I would like the option to toggle "snap to grid" on and off. It's really annoying not being in complete control of the elements when I need to be. Per guides, though not really on topic, it would be nice to have sliding rule guides as you have in Ai and Ps. I have to create a column grid in Ai and import it before I can begin a project. This should be an unnecessary step.
