It would be great to have a few additional options when creating a new SFDC campaign from Marketo (setup tab!). This would include setting the campaign status, as mentioned in https://community.marketo.com/MarketoDiscussionDetail?id=90650000000Px4SAAS. On my end the checkbox "Is Active" would also need to be set, else the campaign would not be visible to Marketo.
I have created templates campaigns in SFDC. It would be great if you could base your new SFDC campaign on an existing campaign. This would then clone certain elements like the member statusses and so on.
