It would be extremely helpful if Power BI provided an option to automatically maintain a consistent spacing (e.g., 5–10 pixels) between visuals when stacking or aligning them vertically/horizontal...
For reference to other spacing options, see InDesign or Inkscape for a wide range of facilities. I think a different approach may work best. A "Minimum margin" feature. For example: You bring two visuals with a minimum margin of 10px together, They snap at a 10px gap. You bring a visual with a 15px and another with a 5px minimum margin together. They snap at 15px. Visuals can opt-out of margin snapping. For example, a bookmark group formatted as tabs may wish to snap exactly to a visual, even if the other visual is specifying a margin.
