"Read-only" or "Static" singles

[thupsi]

I was thinking a bit more about #17304 and yes @brandonkelly was right to point out that this is probably easy enough to add via a custom plugin, or just using custom UI elements if you don't care about injecting stuff into the sidebar, but:

What about having entries that have JUST UI elements and nothing else?

If we could have a setting to make specific single sections "read only" (this should probably disallow adding fields to the FLD and only allow UI elements, while hiding save actions, the meta panel etc) it would be useful for:

• Documentation pages in the CP, similar for example to the User Manual plugin.
• Dashboard pages that live inside a custom index page.

Actually, I've just added a quick version of this to my experimental/proof-of-concept Singleton plugin. If you combine "read-only" mode with the other features in this plugin you can have a cp page called "Blog" and inside that:

• Blog index page (single)
• Blog posts (channel)
• Blog stats (read-only single)

And this would be with a persistent nav so you can move lateraly between the above!

Neat, no? 🙂
