Some websites initiate weird downloads without proper user interaction. It would be great to have the same modal/popup as safari that asks you if you wanna permit a website to download. Maybe it's already on your roadmap. Another aspect is that the popup should appear once per domain so that you are not asked over and over, just the first time.
Heck I just thought of this but it would also be cool if the popup had a checkbox that says "ask again next time " but who knows how useful this actually is.
