Firefox is going to add native tab grouping, as well as vertical tabs and a sidebar. This is very interesting for Floorp. Would Floorp start using Firefox's native sidebar instead of Floorp's custom-made one? And what about vertical tabs?

They will leverage Firefox assets and optimize existing features to those new features.
This is just my guess, but I think it will be something like, the Vertical Tabs will be from Firefox, and the Floorp Workspaces will be added.
