Download button to download custom notebook / markdownfile

It would be nice if we could have the download button on the top-right corner to refer to a custom notebook so that for some interactive pages, which are more likely to be downloaded, a different version of the same file is downloaded without all the jupyterbook additions. Additionally, we might create a script which removes/changes all the syntax which is not supported in the regular python notebooks and the download button would by standard refer to this adjusted file. I wouldn't say this feature has a high priority.
