ON HOLD

Having trouble looking for a workaround. The YouTube API seems not be of any use in this script for the time being.

Youtube Subscriptions Watch Later

A userscript for adding unwatched videos from your YouTube subscriptions page to the "Watch later" playlist.

Tested on:
OS: macOS Sierra (Version 10.12.6)
Browser: Google Chrome Version 60.0.3112.101 (Official Build)(64-bit)
YouTube new Material Design layout

The script is published on GreasyFork and OpenUserJS at:
https://greasyfork.org/en/scripts/33273-youtube-subscriptions-watch-later
https://openuserjs.org/scripts/ackoujens/YouTube_Subscriptions_Watch_Later

Installation

• Install TamperMonkey or GreaseMonkey extension for your browser
• Visit https://greasyfork.org/en/scripts/33273-youtube-subscriptions-watch-later and hit the Install button
• Visit YouTube (or refresh the YouTube page if it's already open)

TODO

• Hover over icon swap
• Deliver feedback when videos are added
  • Delaying video adding on each index might deliver a cool animation
  • Pop up a prompt like the regular "Watch later" one but alter the feedback text
• Check @homepage, @homepageURL, @website and @source header elements
• Add a script icon @icon, @iconURL and @defaulticon (script icon in low res)
• Add a high res script icon (@icon64 and @icon64URL)
• Add @updateURL (version tag required)
• @downloadURL to know where the script will be downloaded when an update is detected
• @supportURL to submit issues
• Add resources with @resource for icon

Example:

// @resource icon1 http://tampermonkey.net/favicon.ico
// @resource icon2 /images/icon.png
// @resource html http://tampermonkey.net/index.html
// @resource xml http://tampermonkey.net/crx/tampermonkey.xml
// @resource SRIsecured1 http://tampermonkey.net/favicon.ico#md5=123434...
// @resource SRIsecured2 http://tampermonkey.net/favicon.ico#md5=123434...;sha256=234234...

• Research if document would run more effecient in different modes

  • @run-at document-start (injected as fast as possible)
  • @run-at document-body (when body element exists)
  • @run-at document-end (injected when or after DOMContentLoaded event was dispatched)
  • @run-at document-idle (after DOMContentLoaded event was dispatched)
