Hi John,

By trying and making my own styles over and again, I learned
gradually. I also had to stare at some other people's code
for a while before it began to make sense. I recommend to
persevere.

Yep, just move the code you had for each of your in/outpoints,
but their feel code should be converted as I said above.
I tried to show the main point of stealing the panes.
Sorry for any confusion.

Well, it is mentioned, though briefly, just before section 7, in:
http://www.rebol.com/docs/view-guide.html
I probably picked it up from code examples more than the docs.
I've got lots of examples of my own on rebsite "Anton":
Determine rebsite "Anton" now and in the future with:
select load-thru http://www.reboltech.com/index.r [folder "Anton"]
;== http://www.lexicon.net/anton/rebol/index.r
Take your View desktop to the returned url, and navigate to
the gui/ folder. There are some simple examples of new styles
in there.
Do this:
probe face
You can see a primordial face and its facets within.
'with is just the layout dialect's way of allowing you to
easily set the facets of a face (or a style) you are building.
These two examples are equivalent:
layout [box "hello" red]
layout [box with [text: "hello" color: red]]
In the first example above, the string "hello" was placed in
the block directly after 'box. The layout dialect sees that
string and sets the box face's text facet to that string.
The second example does the same thing more explicitly.
