A Few Suggestion About Collection & Tab/Memory Management

1-Add #Tags to collection for better categorization and search
2-When user saved a URL in collection and after that when user visits that URL again, with an indicator be remind to the user that URL has saved in collection(Like Bookmark indicator in Omnibox)
3-Add a new option to 'Tab Context Menu' that would allow to user do manually 'Discarding' tab; And before reloading a 'Discarded' tab get reloading permit from user.(I know chromium has 'Auto Discarding Mechanism' and this suggestion is for better tab/memory management by user(alongside by 'Auto Discarding Mechanism')
