Honestly at this point I just miss the api that let you get tab-specific history which enabled MouseGestures to show a context menu on right-click scroll-up/down to go forward-back in current tab. It seems like such a minor thing that there's no reason not to support, and such a huge QOL to keep around. I feel the lack of it on a weekly basis like a decade (?) after it was removed, I'm never gonna get used to not having it.
today non of these extensions exist and similar things are a joke by comparison lacking the large userbase and years of refinement.
then i also frequently have no idea where most of the interface buttons have gone.
i still use it but im far from locked into the ecosystem.
