Hi @felipowsky
Thanks for this. Any particular reason for renaming cornerRadius to radius?

[felipowsky]

Hey @andreamazz,
I have a project with an extension that uses cornerRadius already so I needed to rename it.
I was getting Ambiguous use of 'cornerRadius' when I tried to configured the pop tip.
But I removed this from this PR. It's just the commit that's there.

Right, I didn't notice the last commit.
Cool, thank you!
