    I love this plugin, it’s great.

    Please can you add the option to collapse the categories on all pages except category pages and posts.

    I have edited the code slightly to achieve this by adding

    && !is_page()
    next to the !is_front_page()

    to the collapscatlist.php

    Anyone else who want to do this, here is all the code of collapscatlist.php

    But not safe for any further updates.
