On the topic of copy editing you raise: I wrote a book in DocBook for Manning in 2010. DocBook is XML, so I structured it with opening / end tags on their own line, content in the middle. As you would with a HTML document.
After copy editing multiple chapters, they sent it back to me with all the content on a single line. I was so incredibly upset that they ditched all my painstaking format that I almost abandoned the project there + then.
I already have a mechanical keyboard for one of the two desks, and in the new year I'll only have _one_ desk, so I'll move that keyboard over to there. I don't mind the trackpad, but I've considered getting one of those vertical mice.
I’ve been lightly enforcing a rule of my own too: “no agenda, no attenda”
