 A node is a new term for a page or block because the two now behave similarly. Nodes have the following common behaviors:

+* Nodes are referenced by using `[[]]`.
 * Nodes have a pretty similar editing experience whether changing block content or a page title. In the editing block, properties can be set, `/` commands are available and [new tags](#new-tags) can be set.
 * Nodes have `Linked References` and `Unlinked References` sections. Blocks need to be zoomed in to see this.
 * Nodes can be favorited. For a zoomed in block, use the `Add to/remove from favorites` command.
 * Nodes share the same keybindings for [properties](#property-shortcuts) and blocks e.g. toggling block properties visibility with `Cmd-;`.
+* Nodes can be tagged to become a [tagged node](#tagged-node).
 * Nodes are embedded with the same `/Node embed` command.
 * Nodes are collapsible with an arrow on the left that appears on hover.
 
 Blocks and pages still have some differences that we are hoping to unify like the block view when it is zoomed in.

 ### Pages
 
-While pages and blocks have become more unified as explained above, there are some unique things to pages:
+Things that are specific to pages:
+* Pages have a dedicated view called `All pages`.
+* As seen on `All pages`, pages have different page types: `Page, Property, Tag, Journal and Whiteboard`. Think of these as directories on a file system.
+* Pages are unique as follows:
+  * Page names of type 'page' are unique by tag e.g. there can be `Apple #Company` and `Apple #Fruit`.
+  * Property names are unique and can have the same names as built-in property names.
+  * Page names of other types are unique for their page type e.g. there can be a `#Journal` and a Journal page.
+  * The uniqueness of these pages should be visible everywhere in the app with icons for page types and the display of a page's tag(s).
 * Hovering over a page title shows common features like `Set Property` to add a property to the page.
 
+### Blocks

+Things that are specific to blocks:
+* Blocks are created in a page.
+* Tagged blocks a.k.a. blocks with names do not have unique names.
