[REQUEST] Bookmark all open tabs

[isalew]

As a web developer who uses lots of tabs, I often end up in a situation where I would like to cache all my tabs and restore them at a later point. Currently, I can achieve this with Toby Tab Manager, but my bookmarks are in Raindrop. Ideally, I think these two features should belong in the same place:

1. Provide a "save all" feature to add all open tabs into a collection (should also account for page being bookmarked in other collections)

2. Provide an "open all" feature to open all tabs in a collection (currently, you can do this if you select multiple tabs, but I would like an "open all" button to make things simple)
