#1 I would need to read the file from the disk which I don't think is possible without the user selecting it using a file upload or drag and drop.

#2 This is kind of possible, the bar is per tab because it is injected into the html of the page, but I could make it always show for each tab.

#3 I could make everything show in one line no matter how many downloads you have, I'll probably add an option to make it do that.

#4 This is probably possible

#5 I don't think this is possible, but if I can figure out how to do it I will.

#6 This is unfortunately not possible, I would have to open another window and then you have have to click again to open the file, which I will probably do eventually. Kinda like sites that show a confirmation page when you click a link to a third party site.

#7 Playing a sound should be possible, not sure about a custom sound though, I'll have to look into that.
