Note taking app with some precise features

Question

I've become involved in a new project for which I have to submit some (mostly scientific) articles. So I think I need some sort of a note-taking app, but I necessarily want it to have some precise features. Thus, I want to:
1. Be able to write rich text, with images, tables, colors;
2. Be able to export my articles from the app's format to some popular format like doc or even pdf;
3. Assign tags to my articles and search within the app by tags;
4. Organize my notes/articles in some kind of "notebooks", like folders;
5. Also have an iOS companion, so I can review and even edit the notes on my iPad.
I've been searching a lot and I really can't find "the app" that can do all this. The best I found is Evernote, but it's very frustrating that I cannot export from it to pdf or doc. Also, the fact that you need a Premium account to use it offline, it's quite frustrating.
Thanks and Happy Holidays to all of you!
P.S. I don't know if I posted in the right discussion thread, but I couldn't find one more appropriate.

Answer 1

Unlike many third party note applications for many years now, neither the OS X Notes application or the iOS Notes application "appear" to offer any obvious basic features to organize or categorize their notes, say with folders or labels/tags, to help one in their productivity.
Is this correct?
The OS X Notes Application can be scripted and automated with AppleScript to create folders with the "folder class," but that seems like a lot of work just to get the ability to keep notes organized, especially when such a basic feature should already be part of the application.
But what if someone new to Mac and OS X needed to organize their notes within the Notes application say by creating folders, how would someone do that other than the aforementioned?
And what if someone new to Mac and OS X needed to categorize and/or sort across all of their notes within the Notes application using tags, how would someone do that?
Lastly, what if person new to Mac and OS X, OR better yet, say someone NOT new at all to Mac and OS X didn't want to turn to a third party solution for such two very basic features; is that person just SOL?
