Hi,
On the Note 4, you could save a shortcut (NOT a widget) to the home screen for an Action Note or an S Note. For the life of me I cannot find it on the Note 5. Below is a pic of what I'm trying to explain:

That's a shame that the option isn't available if using another launcher, like Nova Prime...
I agree, however if you use OneNote, you can set a desktop shortcut to any OneNote page. So I have a daily "Quick Notes" page in OneNote that I use for running notes throughout my day. Works on Nova just fine.
You can do it with a little work.... After you do it a few times, it only takes few seconds.
