Hi Steve,

do you have time to join our audio chat today at 3 pm EST? Or when would you have time for a quick chat, audio or irc? Some of your questions have been discussed yesterday, others are on the agenda today.

I apologize for not explaining our writing rules and outline better. And with your questions you identified important issues!

I already copied your text into the objects chapter. There we will describe all the objects you can find in the supplies bin.

This is a misunderstanding, I should have said it more clearly at the beginning of the chapter. In Tiles we will describe the tiles of an object. So we do not call playfield a tile, but will describe the tiles, which are special for playfields, in the tiles chapter (where we will describe every tile within Etoys). 
We do have a list with every tile extracted from within Etoys, so we know we will not forget one. But I just broke it down into several chapters to enable simultaneous editing. It will be re-organised later. We will probably end up with a chapter called "tiles" (or something like that), in which a user can find a description for every tile, and we still have to decide on the order. For now, the idea is to organize it according to the appearance in Etoys, e.g. sub-chapters for viewer-categories and then one or more sub-chapters for special tiles for special objects (thats where the playfield tiles would appear.)

Thank you for sending your mails to the list!

> <bertf> An object is what you create in Etoys by painting or from the supplies flap. or more generally, anything you can get a halo on and script - so everything you see in Etoys.  A tile is what you put in a script, usually commands., but  referneces and expressions are tiles too. Morph is not really used on the user level, it's an implementation detail.
> <scottwal> "Morph" is any graphical object; it's an internal term which unfortunately has leaked out into some of the documentation.   Some morphs are "simple" (e.g. a SketchMorph really is simply a bitmap) but most are nested structures consisting of submorphs which themselves consist of further submorphs, etc.    Thus, for example, a "RecordingControlsMorph" consists of a total of 75 parts, each of them a Morph in its own right.

> <bertf> as Scott said, Player is another internal term. An Object is really a Player + a Morph. The morph being the visible thing and the player defining the Etoys behavior
