I would like to see a Link Map in Blocs. I have long used that feature in another web design app, and it makes it very easy to see all the links going into a page and exiting a page, linked from within the same document.
Why is this important? Because sometimes you will put multiple links to a certain page in your Blocs document, linked from multiple different pages in that same document. You cannot always remember where all those links are in the document. A properly designed Link Map should show me all the pages that have a link to a given page (in the same document). Then it’s a much easier matter for me to visit those pages and change the links, should the need arise.
