What's New in v0.2.0

Built-in browser — log into YouTube, Instagram, X, and other sites directly inside Siphon. No more relying on your system browser's cookies.

Automatic sign-in handling — restricted and private videos (age-gated content, private playlists, "Watch Later", etc.) now download automatically if you're logged in through the in-app browser — no manual cookie setup needed.

Better compatibility — downloaded videos now play correctly in Windows' built-in video player (previously some files only worked in VLC).

Faster, smarter playlists — playlist downloads load much faster, and picking a single video vs. the whole playlist now works reliably.

Cleaner quality selection — video qualities are now labeled the standard way (144p–1080p+), with a clear warning on any quality that may have limited player compatibility.

General polish — tabs, sign-in flow, download history, and various stability and performance fixes.
