Wow, this works great! On Android I recall getting the "simplified page" prompt but never found that to be all that great of a solution but using reader mode with Chrome is pretty neat. You can format it to basically be the same as reading a book from the Play store.

One nit is that if I tab away from the page and tab back the highlighted area is wiped from the reader pane -- assuming I had unhighlighted it in order to start reading.

In Chrome it seems like clicking the pop up is the only way to access simplified view. If you exit, follow a link, tab away, whatever... I can't figure out how to get it back! Any tips? Really confusing that I'm either missing something obvious or the explicit option is missing.

On iOS you can click the icon to the left of the URL input and select reader viewer as well. Hides ads too.
