Keg55, re lamest ever TABLE OF CONTENTS suggestion: open any pages document without TOC somehow added to what-template-where. Use menu Insert > Table of Contents and notice how everything is greyed out. Useless. How can you expect an app that can't link to bookmarks, or even link to local school and office files, how can you expect that app to build a TOC? Without normal text editor linking capabilities, Pages is stretching it to earn the label postcard app. No, not even a postcard app, really, since it can't add content to interact with local resource, and online resource (excepting HTML page). I think the Pages Team got spooked, when the 3D printers started working - they all jumped out the window. Wating for Apple to hire at least one Team member with the resume item, "Programmer". For now, Pages is drifting in La-La Land.
Not to worry. The Apple operating system actually allows linking. So you can use some other editor. Here are some that allow normal bookmark linking...
Notepad++, BB Edit, UltraEdit, EmEditor, Sublime, Word, Text Editor, Boxer Text Editor, Ultra Edit and so on (and on, and on). Comprehensive internal and external links in technical terms are a must have for application compiler integration, and as noted (or assumed) in Wikipedia, you have at least a hundred Pages replacements to pick from on this page, Comparison of Text Editors (see Programming, Compiler Integration), and on this page, Comparison of Word Processors (see Characteristics, Cross Referencing).
Please allow me to digress for a minute. A basic WYSIWYG work-flow feature seems to be missing, or improperly applied in Pages. Not that I am extra brilliant or anywhere beyond that amazing SFU Programming 101, but it seems natural (to include with bookmarks and local file linking) a one-click style pane. Or even just a simple drop down text menu style elements pane in Pages (which would fit so well with El Capitan Pages): for example, including selection text or tiles for titles, sub-titles, headings, block quotes, paragraphs, normal, code, content (e.g., image) block. Style pane in Word even includes painless right-click on style pane item to 'Update style to match selection...' Idea, Apple, idea! Sublime includes the same thing, in a programmer's key press. Yes, inline, work-flow styling method using standard style items, including user work-flow updating is pretty much across the board now, integrated in user interfacing with that linking, so missing in Pages. What did you say that style pane is doing?
Excuse me, if my rant seems a little aggressive. I did see a $29 price tag on Pages somewhere. Yes, it has a polished look. But no. Without standard linking capability, this app is going to disappoint digital authors. Apple has received tens of thousands, perhaps millions of requests. Why was that basic linking capability removed? One can only wonder.
