1. It introduced bugs where keyword which is added to the list isn't tagged with checkmark in the list (fixed after my chat with support).
2. It removed ability to add/remove keyword to the list by just clicking the list name in context menu. Now to delete every keyword from each list you have to open each list manually, look for the keyword and delete it instead of just clicking the list name as it worked for years now. Removal of this has no logic and is not a feature as support stated. It's a bug and needs to be fixed.
