Bookmarking selected tabs to existing folder

[Kira1098]

Would it be possible to allow for bookmarking of selected tabs to an existing folder, and not just a new folder?

Adding an option in the right-click context menu to 'Bookmark All Tabs' would suffice. (Bringing up the bookmarks list so you can select which folder to add the bookmarks to.)

Inessential additions: allow for this by using Ctrl+D, 'Bookmark This Page' toolbar icons and drag and drop. (Others users might want to be able to click on the star at the far right of the URL bar to add bookmarks to the 'Unsorted Bookmarks' folder.)

Thanks,

Kira

Tree Style Tab https://addons.mozilla.org/firefox/addon/tree-style-tab/ provides the ability, so WebExtensions-based MTH also can implement same UI. However currently I have less motivation about it...
