• When features are renamed or inverted in our code:

  youtube/background.js

  Line 29 in 3c3e013

  # IMPORTING OLD SETTINGS

  
  

  youtube/background.js

  Line 36 in 3c3e013

  chrome.storage.local.get('hideSubscribe', function (result) {if (result.hideSubscribe === true){ chrome.storage.local.set({subscribe: 'hidden'}); }});

linked code is broken :) runs every update:
Lets say user had hideSubscribe = true, extension updated and subscribe = 'hidden' was set, then user switched subscribe to 'normal', then another update came and users subscribe 'normal' was again overwritten by 'hidden'.
limit_page_width correctly calls chrome.storage.local.remove(['limit_page_width']
fix #2121

didnt remove hideSubscribe just in case of rolling back

missed one rename #2156
also autoplayDisable could use some more readability #2157
