Is there a way to hide an element when you click basically anywhere outside of that element? I'm trying to make a popup menu that stays visible until you choose a menu item or click somewhere else on the canvas. 

There's canvas-level interactions, but not one for Click (Tap). This would be the most obvious way for me to achieve this. Click (Tap) the canvas to hide the element.

When creating an interaction, I would expect that the item I'm about to choose for "Selected Item" would be highlighted in the main window. But it is highlighting the item I'm adding an interaction to, which makes it difficult to know if I'm selecting the right thing. 

In the example below, I'm about to select "Menu Item - Home" using the targeting tool in the Layers panel, but "Menu Item - Efforts" is highlighted blue.

I need the ability to resize images when they are part of a component. I'm using SVG icons as images but not all icons have a square dimension.
