+ Precautions.

 There are the following differences in the items displayed by right-clicking depending on the browser.

    Opera            : "Copy link address"

 Videos whose playback is restricted cannot be played with this app.


+ Simple usage instructions.

 Start the app and press the icon on the top right to open the YouTube homepage.

 Right click on your favorite video and select "Copy link" to copy the title.

 The same is true if you right-click on the movie that is playing and select "Copy URL of video".

 When the list to be played is completed, you can check it with "Play".

 Unchecked titles will not be played.

 The file saved by the "Save" button is played by double-clicking.

 The selected title list can be deleted with the "-" button, and the order can be changed with the "▲" and "▼" buttons.
