Similar to how we are told where forms are in use, it would be nice to see a list of emails and landing pages where specific files and images are in use.
That actually works today (sort of) - but only if you insert images/files by dragging the image icon from the right toolbox area into your email or landing page. If you're like us, it's easier to just find the image in Design Studio, click on it to get the image URL and then paste it in our assets. Using this approach, however, will not allow Marketo to track where the images/files are used. This is a much needed feature.
