Default to no action button

[probablykasper]

This makes it so that no action button is shown by default. Previously, I don't think there was any way to avoid having an action button?

Breaking change for those who want to keep the Show button

thanks, this is a welcome change! I'll merge this manually, since I need to change the commit message slightly.
