Rated 5 out of 5 stars
I've tried to find a way of contacting the developer, but have had no luck.
It'd be great to get optiosn to :
1) set minimum item width
2) show only x most recent downloads
This way when downloading lots of things, after x downloads, the items fall off the download bar, instead of wrapping, so prevent the toolbar growing in size using up all the screen.
Otherwise this addon is incredible, and far prefer it to the horrible new download panel thing Mozilla are doing.
