Hi,
because I did not find a hint in the theming tutorial here is my question:
The ZPBoostrap theme for example uses its own comment form which is located in the themeroot/comment_form folder.
I have made a change to the related_items.php file from the zp_extensions directory which looks good (for me) with Theme A but not with Theme B.
I tried to copy the modified file in the theme root directory but this does not work.
I am not sure if this will be possible...
