Ok, I was thinking over it again.
Can you probably suggest changes in the module so that if there is a category selected, main part of the module with categories isn`t shown?
And Is it possible to alter the way Items from the selected category are displayed?
I mean anything else except the actual 1 column of full sized articles.

Update. Ok, I achieved that by editing theme3.php like:
<?if (strpos($_SERVER['REQUEST_URI'], 'index.php')!== false){?>
<div></div>
<?}else{?>
<div>/*your original code of the module*/</div>
<?}?>
Also categories view was to be configured in categories themselves, catalogue mode = yes.
Thanks for attending anyway!
