Fixed aspect ratio

Select a fixed aspect ratio for your dashboard and:

Anticipate the end of the visible page while editing, so your tiles don’t introduce scrolling in view mode.
Define a default format for exports.
Visualize the page boundaries used for export.

Stack up tiles

Keep your dashboard compact by removing vertical gaps:

Enable 'Stack up automatically' in dashboard settings (applies to all tiles across all pages). Tiles will then be rearranged whenever they are moved or resized.
Set the default behavior for new dashboards in your user settings.
If disabled, you can still use Stack up tiles manually from the page or group tile context menu.
