Great and Useful Extension! Rated 5 out of 5 stars

I really like this extension, and am really grateful to the developer for all the hard work! I have a few suggestions, if you don't mind? ;)

* an easy way, with a single click of the mouse, to show/hide the bar (sometimes I am not near the keyboard, so can't use the shortcut)
* in addition to the information when downloading, it would be good to have "remaining to download" and "total" filesize, possibly in the format remaining/total ie. "175 / 320 MB"

Other than these minor points, it's perfect! Thank you again! :)

PS. For users on Ubuntu/Linux 12.04, the steps to configure Download Status Bar with the Clam antivirus scanner are here:
