Yeah, you can pull up the window through the menu system, but that is not how it used to work. You'd click to download something and it would automatically pop up, and stay up unless you closed it (sometimes I forget that I am downloading something).
Also, there used to be a pause BUTTON. So saying you can right click to pause a download is not the same -- it's more clicks to do the same action. Also, I did not see this in the add-on, only in the new library window. Again, that's multiple clicks to do a job that used to take one click.
One more difference I forgot to add -- the ability to clear the list of downloads is also not available in this add-on. If you download a lot of files, or even if you are paranoid and have privacy concerns, then it's nice to clear that out.
All I was trying to say is that it seems pointless to have an add-on that LOOKS like an older option, but doesn't have ALL the functionality that the former downloads window had. And when you write an article basically saying this add-on fixes/replaces that, is not telling the whole story.
