Add the ability to set fields on a navigation level, not only a node

[jan-dh]

What are you trying to do?

I have a complicated setup with a navigation that's shared across a lof of diferent sites. Depending on what site it's used it should behave differently. Right now all that logic ends up in the template and isn't very flexible.

What's your proposed solution?

I would love to have the ability to be able add some fields to a navigation (not on a node level but on the navigation level) so I can add the logic to the CMS

Related to https://github.com/verbb/navigation/issues/201, but not currently possible. The biggest reason for not making Navigation's themselves elements (that could support custom fields) is performance.
