Solid. Powerful. Learning Curve. Better than the alternatives

I have been using this app for 5 years along with its competitors, and now I am only using this one. Here is why:
- It has a solid file structure that I can access on Dropbox from within the app, or from outside.
- The storage structure is transparent and files are transportable. This cannot be said about either of the big competitors.
- The Dropbox sync is flawless. Not true of one of the competitors.
- I love the way it extracts tasks from my notes! I can always refer back to the note to remember the context.
- All files -- PDFs, word, pages, excel, numbers, etc. -- are visible from within the app.

What could improve? A more sophisticated search would be helpful. What it has works adequately.
