Can you guys add a nice little spoiler tag to this ribbon:

This can be used when someone wants to put their code (for example, as a solution from buckys homework or some other solved tasks) but not everyone wants to see it right away.

With a simple toggle button of "Show Spoiler" or "Hide Spoiler", it will display/hide the content within the spoiler tag.

The spoiler tag doesn't have to contain code only, it can contain whatever is in there.
