Single and attached to bookmarks

Raindrop is bookmarks' centerpoint for me. Native bookmarks are still useful, though. I'd prefer them autosynced to raindrop.

Allow saving all of the current window's open tabs links without having to through each tab and saving it individually. Likewise, one should be able to open all selected bookmarks in the add-on (each on their own tab). This is essential to easily switch between contexts or to research and quickly save a set of bookmarks that refer to a given topic.

A feature that would allow the user to highlight text on articles and save the highlighted version.

Feature to view all bookmarks saved in the nested collections within the selected collection. For example: Primary Collection -- Nested Collection 1 -- Nested Collection 2 Option 1: Clicking on "Primary Collection" will show all bookmarks from Primary Collection, Nested Collection 1, and Nested Collection 2. Option 2: Link above bookmarks in Primary Collection or in "View" menu may be clicked to show all bookmarks from Primary Collection, Nested Collection 1, and Nested Collection 2.

In this time, I am on the horns of a dilemma cause I want to add my bookmarks into multiple collections without duplicate them. I'd like that feature as soon as possible =)

Reminders for saved items.

Multi Authentication with Google Authenticator to safely access public PCs too because even if a public PC is infected with virus, they wont be able to login into account unless they type in 2nd authenticator access code.

Different Profiles/Identities, LastPass does this feature very well. Preferable it would work like this : You have the main one with all your bookmarks then have a different profiles/identity, say.. work and home that you can easly switch back and forth from, optionally you have an option to fill in password everytime they switch, maybe with a "don't ask me for password for the next x amount of mins". You can add Groups and or categories to different profiles..
