Smartphone browser: full screen

In horizontal/landscape mode, that I use for “hyperlinking” a star’s name in a message, I feel like a lot of space is not used for NP2.
Would there be a way to (optionally) toggle full screen for smartphones (somewhere in the menu?) so that 1. notification bar, 2. URL bar and 3. system buttons would disappear?

(example: LG G2 with 5.2 inches and 1080 x 1920 pixels)
