For the Icon what is supposed to happen??

okay so I was trying to add in an icon in both of the two new modules. I double clicked on an icon. I even tried a triple click and nothing seemed to happen.

I did see a spot below the icons that you can put some text into it and thought some unicode text would AUTOMATICALLY go into that spot. Never occurred.

I tried proper unicodes in that spot and it did work for sure.
