== Overview ==
This group of tasks covers the basics of [wiki:TIMELINES Timelines]. It describes the model (internal structure) and the user interactions (external structure) related to timelines. After this iteration we should have a prototypical timeline model with a simple user interface to demonstrate it.

== Task requirements ==
In this revision, this task should create:
 * an "Open Timeline" button in the timeline palette in the timeline tab that opens the bottom flap and shows the page's timeline.

The timeline flap should consist of:
 * a channel for every text frame on the page with a label.
 * a subchannel for the frame's visibility property.
 * a playhead that can be moved across the timeline from 0:00 to 1:00.
 * a control bar for the selected subchannel with two fields and four buttons: 
  * a field where the user can enter a start point (by default 0:00)
  * a field where the user can enter a stop point  (by default 0:00)
  * a "show" button: if clicked this will make the frame visible from the start point to the end point.
  * a "hide" button: if clicked this will make the frame invisible from the start point to the end point.
  * a "show all" button: if clicked this will make the frame visible for the complete duration of the timeline.
  * a "hide all" button: if clicked this will make the frame visible for the complete duration of the timeline.

By default, all frames on the page are shown all the time. If the user changes a frame's visibility, this will be reflected in the frame's channel.
