Create a keyboard shortcut to close download bar &/or have bar close XX seconds/mins after completion

This is pretty straight forward but I’d really like the download bar to close after completion of downloads. If you want to keep something on the screen as a reminder, may I suggest an icon above the bookmarks? I’d like to see it close immediately after d/l is complete, or maybe have a time setting users can select how long until it closes.

Another good addition would be a keyboard shortcut as many people don’t use mice while on some pages, so closing it can be a bit of a pain in the back, especially if users are very efficient in using keyboard only browsing (using shortcuts).
