Hi!
Many things are in developpement to enhance Theme Packs.
And i will soon open a documentation about this, and add articles to help users who want to create a own theme pack.
Today, (but all is in developpement, so will evolve) you can check this file : SITE/add/elements/icsetvar.php
This is where i will add all possible data to be called in a Theme pack with a new style like
$EVENT_TITLE
But many other function still could be called using $item->'name'
The list of function is in SITE/models/list.php
$START_DATE is not yet added in new icsetvar file, but your can use $item->startDate, $item->enDate, $item->startTime...
All this need more enhancement, more possibilities, and a documentation to explain it. All this is in developpement, and i add new things frequently.
My goal is to have in 4 or 5 months, a good system for designer of custom theme packs (because Theme Pack system could already be a powerful feature to do what you want with iCagenda, but not today easy to understand
)
Regards,
Lyr!C
