I just watched a recording from the Marketo User Group Youtube Channel and it was said that you cannot re-order the fields in a List View. And that is true in a way. Let’s see:
This is the dialogue where you create or edit views. And it would be intuitive if you could arrange the order of fields that are visible columns in this window. But you can’t.
What you can do though is navigate to your view result, grab your column head and drag and drop it to the desired place. This is not only a one-time action but will reflect back on your list view for all subsequent cases. Easy, right?
And yes, List Views should be shareable! If you agree, upvote here.
