Add double-click default action in jupyterLab

[dhirschfeld]

In JupyterLab it would be great if voila could register a handler for .voila types and allow users to choose the action - e.g. open dashboard in a new browser tab.

A user who wanted to opt-in could then save (/distribute) their notebook with a .voila extension.

So a user could run the dashboard as a normal notebook, an "Open with Notebook" context menu for .voila files should also be registered.

Thanks @dhirschfeld.

This sounds like it would be quite useful indeed.

Otherwise it should also be possible to specify the default renderer for a file (the preferred widget factories) in JupyterLab users. So users could choose to open .ipynb files with the voila preview.

I'm not sure you'd want to open all notebooks with voila preview by default which is why I suggested letting the user opt-in by renaming it with a .voila extension.

A user can already choose to open a notebook with voila using either the button or the Open With menu:

If you want to distribute it as a dashboard application though, it's a bit awkward to tell a user to first open the notebook and click the voila button (or to open with voila gridstack in the context menu) which is why I think there's a lot of value in some way of making a voila notebook open by default (double-clicking) with voila... without changing the behaviour for all other notebook (.ipynb) files
