It would be nice to be able to duplicate a row or text card to be used somewhere else in the site page. If you configure a text card with HTML and CSS you can copy the code and paste it in a new text card at least but you cannot copy the appearance properties of a row in order to use elsewhere in the site. It would be helpful to have a duplicate option similar to dashboard where you can quickly duplicate a row or layout item to move and quickly reconfigure the properties if needed without having to start from new each time.
