Thanks @brichet for the report.

Probably the html-extension could be added to the application here:

notebook/app/package.json

Line 107 in b14def0

"dependencies": {

pdf-extension seems to be listed in the dependencies, but maybe it's not properly included in the build.

Thanks for the suggestion @jtpio, it was enough for HTML Viewer.
I'm trying to figure out what's going on with the PDF, it seems that the docmanager.open command isn't catching the correct file type.

Thanks @brichet for the PRs, both #6584 and #6583 are now merged.

I'm happy to start a new Notebook 7 pre-release to help with jupyter/nbgrader#1684, unless there were a couple more fixes you wanted to submit first?

Thanks @jtpio.
I'm working on a way to open the file browser tab when changing the path from an other tab, and also to open the new tab by default after its creation.
So if you can wait a little longer, that would be great.

Sounds good, thanks again 👍
