Hi,

I changed the style of the progress bar (thanks to mederi) and added the behaviour of searching automatically when starting the extension. For easy downloading and closing the extension, a new button is introduced in file hash mode.

I renamed the Ok button in IMDB mode to more describe it has more functions.

Perhaps you can integrate them in your version?

Hi,

Thank you for this first pull request.
As you may have noticed in the last upadte I didn't push all your code but I take your remarks into account by putting mederi style progress bar and trying to make the interface more intuitive.
