[Radiant] Ordering of pages

[Anton J Aylward]

How can you order pages under a <r:children:each> ?

I can see the "by" parameter but what does that amount to?

I can see that it could be the title or the publication date, but what I'm
trying to do is a a bit different that that.
Let me express it as a general problem.

Can I do something like create a tab for each page under a parent, call it
"sequence" and put a sequence number in it?

Can I do something like select the single item from a list of pages
describing events that is the next one if there is a tab that has the date
in it?

Can I control the order of menu items ?
