Mat/TT,

I will keep the details under my hat until I develop the idea in my head a 
little but I am playing with an idea I call Ghost tiddlers, since Shadows 
is a term already taken. I am raising it now because it sounds it could for 
part of these discussions with image layers. My terminology is all mixed up 
as I explore these ideas.

Ghosts are almost like 3D tiddlers. 

   - Basically you use a namespace such as $:/ghosts under which for every 
   tiddler "tiddlername" you can you can have another tiddler 
   $:/ghosts/tiddlername.  
   - When I finalise my Tiddler Serial Number tools this will also be 
   rename independant.
   - My idea was so I could annotate the primary tiddler without even 
   editing it, and add number of other cool features.
   - With appropriate design the number of Ghosts for a single tiddler 
   could be infinite. 
   - The serial number can have a depth/layer/level number SN/0 SN/1... and 
   even this could be reordered with drag and drop.
   - The result the user can see can be programed in the view template as 
   desired from a combination of the depth tiddlers.

Why mention them now?

   - Such a facility would be helpful for text, however with smart design a 
   ghost/or layer tiddler could have a background, that's displayed behind the 
   foreground content, and one could edit the image on the midground tiddler. 
   Which layer is for edit now could be a simple switch like layered image 
   editors.
   - Keeping such a design in mind provides guidance to the way we should 
   provide an image editor for tiddlers, where the result has an invisible 
   background that we could stack layers or include a fixed background.

Just thinking
Tony
