The eyeball When you use a module to the left of the “Save and Exit” you will see an icon that looks like an eyeball. If you click it (takes a little time) you will see how your page looks on a computer screen, a tablet, and a cell phone. This can be handy specially to see how a photo will look.
Also, always remember to name you module. At the bottom where is says “Admin label” leave the type of module but add a short description. By doing this you can easily find the module you need from among many on a page.
