Good idea. Do you mean our first-party plugins (Spyder-Notebook, Spyder-Unittest, etc)? If so, this could be included as a table in the Plugins index page, which would also be useful to link to each plugin (even the ones not currently documented) and perhaps briefly summarize its purpose.

Thinking about this it could be nice to have a list of external plugins in fact (including does that could be around but we don't maintain directly). However having at least the external plugins we maintain could work too 👍
