Display when leaving page

Hey,

Forgive me if this seems like an ignorant question, but currently the bar only displays once the new page is visible (while loading content). Would it be possible to display the loading bar when leaving the previous page?

When doing something like uploading a file from the front end (not that this plugin is intended for this use), it can take a minute or so of ‘Document: xx%’ loading of the confirmation page during the upload process, and currently using this plugin you only catch the last few seconds of that once the confirmation page is displayed.

I hope I’ve worded that well!

Thanks
