Instantaneous YouTube Quality Resolution (IDM-style):
Added instant client-side resolution from the YouTube player data and metadata on initial load and page navigation, eliminating the previous 5–10s inspection delay.
Automatically kicks off silent background prefetching to prepare the verified stream URLs, ensuring qualities are immediately ready when the download button is clicked.
Added in-memory caching and in-flight request resolution in the background handler so instant quality clicks transition directly into downloading.
Redesigned Floating Download Menu:
Replaced the previous bulky rectangular panel and basic buttons with a modern, glassmorphic card design.
Styled the floating "Download this video" trigger into a sleek pill with a crisp download glyph.
Redesigned quality choices into interactive rows featuring color-coded resolution badges (4K, 2K, HD, SD, Audio), format tags (MP4, M4A), and smooth hover animations.
