Stackable shortcut S

Stack placeables on top of one another by changing the Stackable attribute to True.

Shortcut, use S. Select the placeable and press S (this changes the "Stackable" option to True). Then, just copy and paste the placeable as many times as you want.

Stackables or placing things on tables

You can now stack placeables. This requires only changing Stackable under the miscellaneous properties to TRUE.

Change the default Stackable to True for the item, such as the bowl of fruit, which can be easily placed on top of say a table. This really works, see screenshot.

You can even stack several things, like baskets. A stack of three of the flatter baskets looks good.

OK, it is sometimes easier than other times. Use the arrow keys to fine tune your placing. And Ctrl arrow to turn it around.
