= Analysis =

== Overview ==

All frames have a frame anchoring halo which allows a frame to be anchored. This means that the frame will be associated with a particular point in another frame. There are different modes defining how the frame should move according to the frame it is anchored to.  

== Task requirements ==

 * When a frame is selected the rightmost of the halos that appear over it should be the frame anchoring halo. It should be represented as a small anchor icon. 

 * The user should be able to drag the halo to the an apropriate for anchoring place in another frame. Frames can only be anchored in a flow frames or a non-flow frames.

 * A subsidiary line should be drawn between the two frames. It should not be visible in Reader mode.

 * The anchoring point should be kept. For R0 this could be the frame in which the anchor halo was dropped in.  

== Task result ==
The result of this task is source code.  

== Implementation idea ==

Add new halo to the frame halos which colud be dragged and dropped. Add a property into the FrameView of the anchored frame referencing the frame it is anchored to.

== How to demo ==

 * Select a frame and show the anchoring halo. Drag it into another frame and show the line connecting the two frames.
