I wanted a page that would list all of my projects, but I didn't want to have the additional effort of maintaining it and I didn't want to risk it going out of date. Fortunately, with Twig, it's prety easy to have a page be automatically generated based on it's children.
Now, all I need to do is create child page within my "Projects" folder, give it a short summary to describe what the project is, which is useful anyway, and then the entry will be automatically added to the main Projects page.
At some point, I might make this a bit more complex, with sections for different types of projects (eg. Python, Grav, Raspberry Pi) but for now this suits my needs.
