Add the possibility of tagging features and lines/systems as "projects"

[BrunoSalerno]

This should display them as a separate group of things.

UPDATE: I think that tagging systems as "projects" would be enough: they wouldn't be shown by default and would be listed below non-project systems. They should have a "project" label or something like that.

I think that something like "proposed" or "fantasy" would be better in this case, as this system seems to be an invention of the person who put it in there. I think "proposed" for those systems that have actually publicly been proposed by people who could make it happen and "fantasy" for private citizens' ideas would be good.

It is still not clear how the years of the features belonging to to these systems would behave.
