Hi there,
I appreciate you reaching out. I sincerely apologize for this oversight.
1 - How can I link images / titles to an external URL? I don't want to go through the 'page details' of each item.
Sorry, right now this feature/functionality is not available.
2 - Videos do not play!! I included a youtube link in the Portfolio item settings, and though the 'play icon' is visible, the video will not play (Don't know if a modal-popup is supposed to be come up there). Thank you.
Please make sure your video source from the youtube or vimeo.
-Thanks
