How Do I Open Apps In Full Screen By Default?

How do I set ‘open full screen’ in Notes, Messages and other apps(eg. Feedly RSS reader)? I find it annoying that they open in small useless windows in the bottom right corner of my screen and I’m constantly have to manually enter full screen through the menu bar. Thank you, Murray Wight, Australia.
I find these apps pretty useless in a small window. I prefer full screen views and being able to have apps to default to full screen on opening would be great.
