Hello,

The extension operates using a tab action to display only the icon when needed. The 360p resolution is a limitation imposed by YouTube. Higher resolutions can be enabled through the extension settings, but without audio (due to YouTube's restrictions).

When the pop-up is open, an external server attempts to download the video in 1080p, which I believe is a reasonable solution. A percentage indicator is shown, and if the download completes successfully, you can download the 1080p video for free, unlike other extensions.

The option of merging video and audio to create higher-quality downloads was considered but discarded, as it would "overload" the browser. The goal was to keep the extension lightweight.

For any requests for assistance, please use the means provided.
