Default [Q] Integrate Phone and Tablet

So, I have a Moto X, on Verizon, running the latest 4.4.2 (so I unfortunately cannot root it or anything), and a Nexus 7 (2013). I have both, and generally use my tablet more for general reading and web surfing and such, while on WiFi, since I experience poor screen on time on my phone (even on low brightness). However, I was curious if anyone had any interesting modifications, or hacks, or any sort of making their phone and tablet operate more together. Thanks for any tips or tricks!
