This is my absolute #1 wish for my phone.
I want to load up 30 news tabs before I hop on the subway and just have them all stay loaded, instead of the most recent 4 staying loaded, while any others refresh (and fail) if I switch back to them.
I absolutely want all of my tabs to have the page state cached in storage whenever I leave them and they're done loading. With the scroll position too, as I'll often be interrupted halfway through reading a long story. I don't want them to be stored ephemerally in memory.
Surely it can't be so impossible to "pickle" the state of the page and then unpickle? I can totally accept it not surviving every app upgrade too. Just let me load up stories on the subway platform and read them all on my underground commute.
