Use minimal taps: Make the downloaded video available in just one click after pasting or searching.
Prioritize clarity: Use simple icons, labels like “Convert to MP3”, “Save Playlist”.

Use progress bars, success/fail status, and clear download history.

Allow search through downloaded files offline
Use the in-app browser or the YouTube app redirection for watching or selecting videos
