v3.5.0 fixes the two bugs reported in your reviews:

Fix: refreshing the page, or opening a playlist video in a new tab, no longer jumps to the next video of the order. YouTube recently started rewriting the playlist position in the address bar on every page load, which the extension misread as YouTube auto-advancing; it now follows the video you actually chose. Reverse, shuffle and custom orders still advance as designed when a video genuinely ends.

Fix: after a refresh, the end-of-video advance no longer replays the same video — positions now come from the playlist panel itself instead of the address bar.

v3.4.0 adds three features:
• Disable autoplay — a new setting stops each playlist video just before its end instead of rolling into the next one, whether the order is YouTube's or the extension's. The end of a Reverse or Shuffle order now holds as well.
• Button visibility — hide any toolbar button you never use (Reverse, Shuffle, Sort, Reorder, Reset, Save, My Lists, Duration, Load All, Add to Playlist) from the popup's settings.
• Settings travel with backups — Export now includes your settings, and Import restores them together with your playlists.

Fix: the Add to Playlist button now always sits under the video next to Like and Share; it could previously land in the playlist panel header and squeeze the playlist title.

v3.3.0 adds six features:
• Sort dropdown — order a playlist by title, duration, channel, or watched state.
• Load All — resolves every item of a lazily-loaded long playlist in one click, so Reverse, Shuffle, Sort and Save act on the whole list.
• Watch-time pill — total, watched and remaining time, with 1.25x/1.5x/1.75x/2x estimates.
• Playlist overview pages (youtube.com/playlist?list=…) now get their own toolbar: Play Reverse, Play Shuffled, Save Snapshot.
• Local playlists — build a list of your own from any video you are watching, using the ＋ button under the player or the popup. It is stored only in your browser and plays from the extension's own sidebar.
• Move to Top / Move to Bottom buttons in Reorder mode.

Fixes: saved snapshots no longer inject rows into YouTube's sidebar (which corrupted reverse, reorder and the item count); playing a snapshot of a real playlist no longer shows a duplicate sidebar; overview-page actions load the full playlist before acting; playlist and search pages read correctly after YouTube's move to the new card layout.

v3.2.0: Add tags and name/tag filtering for saved snapshots. Saving a playlist with existing snapshots now lets you update a specific snapshot or create a new one. This release also fixes My Lists button state, Firefox popup storage, reversed-order snapshots, drag/drop ordering, SPA navigation races, and backup validation.

v3.1.0: Resume where you left off — a one-click prompt jumps back to your last position in any playlist (per-playlist, stored locally, can be disabled in settings). Import/export buttons are now also available in the in-page panel, and a new Duplicate action clones any saved snapshot so you can build variants of a list.

v2.0.4: Added dynamic localization (EN/FR/AR), reactive settings panel in popup (language, auto-skip watched, compact layout, watched badges), safe playback redirection from any tab, and premium UI visual polish.
