I just updated the website with a new feature that will allow you to provide redirects on your posts.
Here's an example of how this can be used. Say you have a craft on the website called Craft A and you make some tweaks and upload a new craft called Craft B. You can now go to Craft A's page, click Edit Redirect, and then link it to your new Craft B post (screenshot). Then when someone visits Craft A, then will see a page like this letting them know there is an updated version of the craft and give them the option to visit the old craft or the new craft.
Awesome!
