Normal i don't have the biggest talking when a UI change.
But think the new Marketo UI to createa a local Asset in Marketing Aktivites is not thinking threw probelly.
Now as a user i need to know what name of a template i want to use. And be surre that this is the one. Since the Preview Buttonis not there.
This dosen't help that you can undo or change a E-mail template when you first have done it.
