I will REPEAT what many others have said.....................

The old version let me do what I want to do, which is download the video and the extracted audio. It also REMEMBERS where I last saved a video/audio combination, so I don't have to keep traipsing around my hard drive to find the place to download.

WHY would you take a perfectly good program and break it so that it is only useful to complete tech-heads? It was fine before. It did what needed to be done. I have fiddled with this new version for about an hour now. I am done. GDit. I am so tired of having to go find alternate versions of things after the good version is broken by "improvements." What is wrong with "you people"?

The instructions say:
1. After installation, go to the options page and
-> 1. Install the native client (This is a small NodeJS client written by @andy_portmen)
-> 2. Install the FFmpeg executable
2. FFmpeg integration is required if high resolution video or audio files are preferred.
My questions are:
Where do I find the options page?
What is FFmpeg integration and how is it done?
