I had a vague feeling there's a function in View to do this, but I may
be wrong. Anyway, the following isn't too ungainly...
>> rgb: "#ff00ff00"
== "#ff00ff00"
>> binary: load rejoin ["#{" next rgb "}"]
== #{FF00FF00}
>> to-tuple binary
== 255.0.255.0
Obviously the binary word isn't needed - I just did it that way to
show the interim result. This will do it in one...
>> to-tuple load rejoin ["#{" next rgb "}"]
== 255.0.255.0

The short answer is yes, but you'd have to write specific code to do
it (I think). Hmmm, I did a test a while back to see how big a layout
View can handle. I didn't attempt to make it scroll smoothly, but it
definately can handle very big layouts. Will attach the code to the
end of this, since it's not too long. ;-)

Not sure what you mean by the code "automatically" wrapping. You can
make text wrap and you can set a guide so your styles will be in
line, but neither of those features seem quite what you mean.

What type of series is it? If a block, it should work. If it's a
string though, (which it could be I guess if it started out as HTML),
then you'd need to convert it to a block. ie...
>> series: {text "hello"}
== {text "hello"}
>> view layout series
** Script Error: layout expected specs argument of type: block
** Near: view layout series
In that simple case, just a to-block would work. ie...
view layout to-block series
but with anything complex, you may need to add the block-ends to the
string and use load. ie...
view layout load rejoin [ "[" series "]" ]

This is definately the place to ask.
And now for that test script I did, with full apologies for its size.
(I know, I know - I don't need any suggestions on how to improve on
this, okay?;)
