Markdown preview doesn’t appear to be as easily accessible as it was under Komodo X. When I have a file (README.md) open by itself and no project open, the view menu only gives me the option for a browser preview.
I’ve reset my preferences, restarted Komodo. I’m not sure where to go next.
Also a nice feature to have, is when you open a markdown file the preview icon becomes the markdown file icon ( for better recognition). But I don’t know if it would be worth the effort to implement this kind of behaviour…
