It will not be the same but the google translator extension if you configure it so that instead of translating what you mark it translates the page, it does the same thing that the chrome or firefox translator would do

I feel opera touch as an opera gx more than anything for its interface, could you take a look at it

I understand what you mean and I use the same
in my case I have the "main" and "musical" homepages, one to navigate as usual on the web and another to listen to music on youtube music and spotify, what I did was give youtube and spotify the option to "anchor" the page (I have the configuration in Spanish, in Spanish it is to Fijar la pagina), in addition, I have configured in the opera settings not to close the pages if I close the browser, that way they always remain in that place permanently

I love that idea, although I don't know how complex it would be to carry it out, since it is quite complex to create an android environment on windows / mac as they are of different architectures
