Sure, would you merge contributions if I code them? :)

Yes, sorry, checkboxes.

Imagine a pagelist template with a checkbox for each
page.  I want to be able to select pages from a list
and paste them all to another page to automatically
create a new wiki trail!

Again, usefull to create trails without a preexisting
page.  The user can specify which page with a form
element.

Sure, I do it all the time.  PHP is set to handle it
nicely if you name your form elements like this:

  name="Category[]"

PHP will put each one nicely in an array named
$_GET["Category"] for you.

OK, now imagine a form which sits in a GroupFooter
which allows users to easily Cagtegorize pages in that
group.  The form might have about 5 text boxes named
Category[], and if any of them are filled out when the
form is submitted, than the categories will get
appended to the end of the page.  

This probably would be implemented with a special
cookie based browsing mode which would turn on/off
this form so that it is not usually visible.  It would
really make overhauling categories on a site much
easier.

Another way to do this would be with a single text box
and some special templating feature that could
identify elements separated by commas and potentially
append them each with the same template.  Something
like this
  (:adl csvtemplate "* [[!{Category}]]":)
which would repeat the append for each comma separated
value in the Category text field.

Building on the previous ideas.  Imagine if I am
trying to categorize many pages at once.  This is
particularly usefull for me since I categorize my
photos and I would like to be able to look at them all
and pick out individuals in the photos and use their
names as a category.  Allowing users to view my
collection by person/location...

So, the plan was to have a pagelist with checkboxs
(and thumbnails for each page) allowing me to select
pages that have a specific person on them.  All these
selected pages would create a trail.  The new trail
page would have a form allowing me to input the
category (the name of the person).  This category
would then be appended to all the pages on the trail
page!

A little convoluted, maybe, but each phase is valuable
in its own right and the two stage application of
categories is nice since it allows me to first select
the pages and review them before applying the
category(ies) to each page.

Like I said... I have big plans for your nifty recipe.
:)

Cheerio,

-Martin
