Show file checkboxes by default in the file browser

[jtpio]

Enable the file checkboxes features in the file browser added in JupyterLab in jupyterlab/jupyterlab#12299.

file-checkboxes.mp4

TODO

• Enable the setting by default if there is no user override
• Update reference snapshots
• Check if we can open multiple files (or track that in a different issue)

cc @gabalafou FYI this is what it looks like in Notebook v7

Check if we can open multiple files (or track that in a different issue)

This seems to be the case:

checkboxes-open-multiple.mp4

[jtpio]

A nice follow-up would be to implement something similar to the classic notebook, with action buttons showing up in the file browser toolbar:

checkboxes-buttons.mp4

These actions are already accessible via the context menu, but could still be nice to have in the toolbar so they are more visible.

@gabalafou would you be interested in looking into it?

I'll open a separate issue so we can more easily track this. Maybe this would need some other changes in JupyterLab, not sure there is a signal or a way to know when a selection has changed already.

Thanks!

I'll open a separate issue so we can more easily track this.
