Improved playlist playback and added Guide & Settings:

• Reverse playback now follows YouTube’s native navigation more closely, preserving native Loop/Shuffle transitions and loop-one replay.
• Added direction saving: remember the last direction or save it per playlist, and choose a default direction.
• Added optional “Wrap Next within playlist.” With Loop all enabled and Shuffle off, manual Next wraps to the opposite end in the current playback direction. Disabled by default.
• Redesigned Guide & Settings with a five-video interactive demo, a settings overview, and direct navigation to three settings pages.
• Added “Open Guide & Settings” to the extension toolbar icon’s context menu.
• Identified a reported early playback pause as YouTube NonStop executing a deferred pause. Removed temporary diagnostic logging.

Button & key actions preferences are saved but are not yet applied to playback.

The order button no longer briefly disappears right after a playlist navigation. YouTube's own menu re-render momentarily marks the extension's mount as hidden, and clicks aimed at the button could fall through to the playlist row beneath, interrupting playback. The button now stays visible and clickable throughout. This also reduces the reported "video stops after clicking the button early in playback" issue; remaining occurrences are still under investigation.

Fixed two playback bugs in reverse (↑) mode:

• Skipped videos: with reverse enabled, finishing a video could advance two
items up instead of one, skipping every other video while climbing the
playlist. Each video end now advances exactly one item.

• Frozen playback: after the extension navigated to the previous item, the
arriving video could occasionally refuse to play (stuck at its beginning).
The internal playback hold now always releases within 3 seconds even when
YouTube's navigation-finished signal is missed.

No changes to permissions (the extension still requests none), no new
features, and no data collection.

Release Notes:

• Fixed a brief playback flash that could occur before navigation completed during ordinary reverse-order hops.
• Improved top-of-playlist behavior: with Loop disabled, playback now remains on the first item and displays YouTube’s native end screen.
• With Loop enabled, playback correctly wraps from the first item to the final playlist item.
• Improved compatibility and stability with YouTube’s player behavior.
