[Feature - Extension] Download all dialog

[thiendt2k1]

I want some feature with the download all dialog like above:

1. Ability to copy url ticked from this panel, to create a list of download urls.

2. Even better, allow regex changing the urls, for example, to remove ?a=view, or any tracking suffixes, etc or you sanitize the links by default(though if possible, regex is still preferred)

OK.
