Module development and code questions

i have two questions:

using drupal_add_js, is there a way to add my js file after all of the drupal js files? so that my js file can see the changes made to the page.

how can i attach collapsing function of any fieldset to an object other than fieldset's legend? for example when a checkbox is checked/unchecked a fieldset will open/collapse. (the reverse situation is not important: when the fieldset is opened/collapsed by clicking its legend, the checkbox's status may not change.)

thanks.

I'm just wondering if anyone else feels the same way:

1) I prefer books to taxonomy as *most* of my site is hierarchical.

2) That makes books more logical for viewers and non-techie users of the site.

3) The 'Outline' feature ROCKS!

4) But it would be great to be able to have two parents.

I know that kinda veers into taxonomy territory, but even if it was something like a distant parent, or step-parent (with breadcrumbs still honouring the primary parent), I think it would be a big improvement to the books module.

A few weeks ago I had some inspiration and decided to make a killfile module (4.7 RC1). Today I thought it was time to get it finished: http://pctips.ustilago.org/plonk

The only thing the module does, is keep a user list, mark what comments* shouldn't be displayed and display a block. The provided template.php (& comment-folded.tpl.php) does the rest.

Comments marked 'hidden' by kill_file can be styled by comment-ignored.tpl.php. Folded comments can be optionally styled by comment-folded-ignored.tpl.php.

I've been developing a module that interfaces with a third party application. When a Drupal user logs in, the hook_user catches the login and sets the appropriate cookies/makes the appropriate database queries so the user is also logged into the other application. I would like to remove those cookies when the user logs out but there seems to be a problem.

I am getting the famous

"Maximum execution time of 30 seconds exceeded in "

error message in my customized module which makes ODBC connections to a DB. The error points to the line where the ODBC connections is actually doing "while( odbc_fetch_row( $result ) )" any suggestions on what the cause of the error might be? is it a slow ODBC connection or something I might be doing wrong in Drupal.

thnx!

Could someone help me understand better how this function can be put into Drupal's default node listings, or into one of the common listing snippets ?

function date_header($timestamp, $format = 'F j, Y') {
  static $last;
  $date = format_date($timestamp, 'custom', $format);
  if ($date != $last) {
    $last = $date;
    return $date;
  }
}

I'm having a hard time getting my head around it.

Thanks, Case.

(apologies for the cross post, if anyone picked this up in post-installation questions)
