I love CN!!!
For anybody's interest: I use Win-A for new notes, and Win-Z for the notes window...
Here's some of my tagging tips... ! for urgent, <> for todos, <x> for completed todos (I used to use  but they are harder to hit on the keyboard), #1, #2, for priority, r/ for archiving p/ for projects, @ for contexts, s/ for status, rp/ for archived projects, . (period) for next action
And for something really cool...I use Stroke-It (highlighted on LifeHacker) and made a mouse stroke to simulate Copying, and Cntl-F12 for automatic copying to CN. So if I'm reading something anywhere on the screen (in a browser or any other program) I just highlight, do a down-left stroke with the right mouse button, and instantly CN has captured the text... so cool, so fast. Which brings me to my urgent request. Can we please have a "default tag" so that when snippets are grabbed, those snippets are automatically tagged with some predetermined tag? For me, I follow GTD principles...and I would want a default tag to be "inbox" so that when I search for "inbox" in the tags...instantly my inbox comes up and I triage them from there. As is, I have to find the notes I added through the automatic process manually which slows down my triage and GTD process to a crawl.
Some requests (including the one above):
1) Please keep it simple
2) Default tags (above)
3) Sorting (by date)
4) multiple note windows open (for copying between them)
5) repeating notes (a la alarms, and repeating todos)
Thanks so much for CN... I use it everyday all day. It is my to-do-list, my GTD system, and my knowledge base. Thank you thank you thank you!!!
