It has many features for us as it can be used with multiple browsers, which makes our work easier in general! I think there's nothing we dislike about this software.
Some of its tools are not available or have limited use but they will improve soon enough!! We recommend using imgDownloader if your website consists mainly from small size pictures such like logos; icons etc because most websites these days require those files so don't hesitate at first sight when choosing file types compatible between different platforms (for example mac/windows).
