I think this would be a very useful feature. I tend to use the preview links to share with my development team (local and overseas) since it's easy and light-weight. If we were able to export all of the preview links and page titles into an Excel spreadsheet, it would be very helpful in keeping track of links (instead of having to go in and click the export > preview URL every time.
I guess you are generating a preview URL for each of your wireframe pages. If you want to share a whole project with the preview URL you can enable the sitemap in the Generate Preview URL window.
Thanks - I was unaware of this capability. However, I'm looking for some functionality that would export all of the unique wireframe links into Excel, along with the name of the page. With the sitemap preview, you don't get to see each wireframe's unique link, so it does not help me in this situation. We try to map the wireframe links to requirements, so we need each wireframe to have it's own link, but these links are not exposed in the sitemap preview.
