Add Download Section or Download progress view on files or Download bar
When we click on any file for download then just one notification arrived and then this got disappear. But after this, we can't see that what is the progress of download means is the file got downloaded or download is still working ?. And also after clicking on file for download if we miss the notification then can't know that file has started downloading or not.
So, there should be a download progress symbol on the file on which we just clicked. Or a top or bottom bar for currently downloading file.
