The only thing that I've found that works properly for my use case (regularly switching between three locales and languages) is Kaggle with the lenses. The only thing missing is disconnecting the locale from the language so I can have proper decimal characters but still search for US-specific things. Right now, I have to chose between having 10,000.10 or 10.000,10 and what language/region I'm searching, together, which is a bit annoying.
