== Overview ==
Page templates provide the ability to use previously created pages as templates for newly created or existing pages. This is connected with frame templating and frame property locking.
 * Creating a page template is done by dragging a page from the page view to the page template palette or other ways (file -> save page as template). In further revisions a template editor should be present.
 * Overwriting a page template changes all the pages created with this template.
  * If the template is global, this changes all of the books created with this template.
 * Page template remembers page style and list of frame templates plus frame z-order. Internally z-order is implemented with the list of frame templates.
 * Page templates can be used for creating new books
 * Page HUD gives "Use template" and "Lock" checkboxes that allow a property to be reset to the template default or to be locked to prevent accident change. Use template and Lock are described further in [wiki:FRAME_TEMPLATE_R0] and [wiki:FRAME_PROPERTY_LOCKING].
== Task requirements ==
Page templates include:
 * Page properties
  * frames' templates
  * frames' z-order (result of position in the frame list)
  * background style
   * image
   * color
   * opacity
  * border style
   * color
   * opacity
   * thickness
 * Frame list - List of frames in current page. In this revision deleting a frame from a page with template applied may not be possible. List should be like 
{{{
<template list> + <modifications>
}}}
Modifications are +frame, -frame, etc, but removing a frame from the template and messing with z-order should be done in later stage. Currently, the template being background of other object will be enough
 * In page HUD a checkbox "Use template" should be present for background style and border style.
  * Background style
  * Border style
=== Huds ===
 * "Use template" checkbox When a property is changed, it's "Use template" checkbox is unchecked from the page hud. In a later stage template editor should be present.
 * "Property locking" checked denies modifying properties by accident. - This is related to [wiki:FRAME_PROPERTY_LOCKING_R0]
 * "Use template" and "Property locking" should be present for:
  * background style
  * border style
  * frame list
 * Templates should have way to be saved. Dragging a frame from the page to the templates palette is a good idea, but if it is not implementable now, create a testing way, see implementation idea

= Comments =
From the user point of view it would be cool to allow image borders, probably hard to implement.
