While you're at it, you might want to make sure your dim arrowheads and note/label arrow heads are the same (filled or unfilled), as your attachments shows 2 different ones - just trying to help you avoid another possible raking over the coals.
User friendliness in NX, at least, usually boils down to taking the time to peruse available documentation and time spent learning how to do things the way the software intends, not necessarily how you learned in another software. You won't become proficient with NX by doing it on your own or not having a good understanding of the terminology that's used over and over within the software.
Don't get me wrong, I get where you're coming from - if I were forced to move from my bread & butter, I wouldn't be too pleased. Something to note is that once you click a command in NX, you can immediately go up to HELP -> On Context (or press F1) and that will usually take you to a useful area in the docs. If not, you may have to spend a few minutes looking around for what you want. If you get stumped, post here and move onto another area of your drawing until you get some direction from the guys here.
