Summary

The ability to create subpages within pages, in the 'Pages' feature on a project.

He is a good example of how subpages would look:

The user should be able to create another page within the page by typing '/' just like for other current commands.

Why should this be worked on?

This would really help in grouping together useful project documentation in a more formatted and easier to navigate way.
When you have a lot of documentation on a project it is annoying to have loads of pages with no visual hierarchy.
Especially when you have a large team working on the project, and everyone needs to find specific information.
This lets the user group relevant information together but not have it all visible at once unless you want to see it.
