Hmm, for plain text note-taking it is indeed, but for Rich Text it’s certainly not. In the end it’s important to discriminate what Agenda is and what it isn’t. It isn’t a markdown editor, it’s a styled text editor (see Taking Notes). Note that it isn’t a word processor either. You can style your text without having to know markdown, but you can use markdown as a shortcut for activating styles. We don’t preserve the markdown however, nor do we plan to do so. We feel that, while certainly immensely popular, it’s still for a subset of people. A lot of people don’t know or don’t want to use it markdown. We feel the balance we picked in Agenda works well for most people.
Having said all of that, it doesn’t mean the way we display code cannot be improved and it’s certainly on our list. But also here it’s important to make a distinction as the current style is named preformatted for a reason, it’s not called inline code as it was never explicitly optimised for code. We believe code does warrant having an explicit style that can also feature syntax highlighting for example, we haven’t gotten to it yet however. See also The features we are working on right now…
