When I have a YAML header as below, the build pane has a button "Build book". It is a dropdown list with the available formats. This is as I expected.
However, when I remove the bookdown::gitbook line and I reopen the project, the build pane get a "Build website" button instead of "Build book". And it is no longer a dropdown button. The button only builds the first listed output format. How can I get the "Build book" button without having to list a least one bookdown output format?
site: bookdown::bookdown_site output: INBOmd::inbo_gitbook: default INBOmd::inbo_rapport: default bookdown::gitbook: default
