Feature Idea: Featured project sub-pages

My idea for a feature is to allow sub-pages for your featured project.

For example:
My featured project is https://goofybox.glitch.me/, but I’d much rather it be at GoofyBox.

IDK if this already exists. If it does, please let me know!

This doesn’t exist already but I know what you’re talking about and will get it on the idea board we’ve got for new Glitch work!
