Hi Thomas,

yes, the snippets are not available in the plain text editor. What you see
in the snippets page is the group to which a collection snippets belong:
C++, QML, and Text. The meaning of this latter one is that its content is
pure text and therefore available for both languages, and not that it's a
plain text editor snippet. But now that you say, I wonder whether this name
could be somehow misleading...

Essentially, the snippets work with the support from the code assist API.
The purpose of SnippetAssistCollector::collect is exactly to provide the
items - notice that those from the text group are always added. At a first
thought, I don't see any technical obstacle that would prevent one from
implementing the code assist interface for the plain text editor, but I'm
not sure of the value it would bring...

The snippet overlay is just the graphical bounding box you see when
iterating through the snippets variables.
