Joomla! Documentation™

For me, the Joomla documentation wiki is a complete nightmare. It is really hard to find anything relevant. Try searching for 'screenshot' and then try googling for 'Joomla screenshot'. So I suggest a link goes into https://docs.joomla.org/JDOC:Joomla_4_Tutorials_Project with a more explicit title: Taking Screenshots (or something similar). And don't add _EN there, that gets added later during translation.

For me, the first title and section text are not quite appropriate. Improve implies you can start with an existing screenshot. I would drop the first section completely and start with Four easy steps to better screenshots. Work in anything useful from the first section later. And why promote a Windows only capture tool when Firefox, Chrome and The WIMP have perfectly good cross-platform tools?

More comments to follow if this one seems useful.
