Limit view in backend for users

Hi,
I have some users not administrator who need to insert news and events in the simpliest way. Every user has its news archive and its calendar.
I create a group limited as much as I can, but it keeps to show some things that i don't want:
- 'New archive' in news and 'New calendar': how to remove?
- how to remove 'duplicate archive'?
- is it possible to enter directly in its news archive, without passing to the archive list?
- how to remove filters on top?
- in the news list and events list, how to show only some actions like 'edit', 'duplicate', 'delete'?

Thinking globally: is it possible to create and extension that modify news and events in function of the user group?

Thank you if you can help me...

Ok, solved: i unchecked edit and remove in user group settings but was set yet in user setting.

Another interesting solution that i found in the forum is that: editing system/config/dcaconfig.php:

PHP Code:

---

<?php

// Put your custom configuration here

$this->import('BackendUser', 'User');

if ($this->User->isMemberOf(2))
{
    $GLOBALS['TL_DCA']['tl_news']['fields']['teaser']['eval']['rte'] = 'tinyCustomForGroup2';
    unset($GLOBALS['TL_DCA']['tl_news']['list']['operations']['edit']);
    unset($GLOBALS['TL_DCA']['tl_news']['list']['operations']['cut']);
}

You can use this new version without importing:

PHP Code:

---

if(BackendUser::getInstance()->isMemberOf(2))
{
  // do something
}

Another great suggest from you Andreas ;) Thank you
