= Analysis =
== Overview ==
Autochaining should be more stable
== Task requirements ==
 * Add an item "Autochain" in the chain dropdown and remove the autochain button.
  * The item may be italic in order to be clear that it is not a regular item
  * When autochaining is enabled, a template for this page is automatically added.
   * When the last page is modified, a new template is created automatically on creating a new page for the flow. 
   * New pages appear with the layout of the last page in the chain.
 * When the text overflows, a new page with the same layout is created at the end of the page sequence
  * The page may contain more than one auto chained frame
 * When text is deleted and the flow no longer fills all of the frames on a page
  * If the page has local modifications, it is not deleted
  * If there are previous pages without local modifications, they are deleted (there should not be text from other flows)
 * When autochain is created the last frame of the autochain should be with enabled autochain by default:
  * Create text frame paste. -> Text frame is inserted.
  * Paste text in it. -> The frame is filled with text (visual marker appears (optional)).
  * Click on autochain. -> New pages with same template are created.
  * Paste some text in the already created autochain. -> New pages with frames should be added after the last, because the text is overflowing.
 * Optional - When a text frame is full and unchained, make a red glow to indicate that there is text that is not displayed
  * This glow should be visible in author mode only
== Task result ==
Code
== Implementation idea ==
Make a single method that uses the dry run of HotLayout and recalculates the areas needed for the text flow. It should add or remove pages if necessary.
When auto-chaining is enabled call this method whenever chainging the layout of the HeadTextFrameView.

== How to demo ==
 * First case:
  * Create a page
  * Set custom layout. 
  * Insert an image frame
  * Insert a text frame, put enough text and autochain
  * Delete the text and show that pages are deleted
 * Second case:
  * Create text frame paste. -> Text frame is inserted.
  * Paste text in it. -> The frame is filled with text (visual marker appears (optional)).
  * Click on autochain. -> New pages with same template are created.
  * Paste some text in the already created autochain. -> New pages with frames should be added after the last, because the text is overflowing.
