Featured Image Column Appearing for all Post Types

After installing I noticed tho plugin enabled the featured image column for all posts.This my not be desired behaviour for people you might consider adjusting the code.

I changed these lines:

add_filter('manage_posts_columns', 'cptbc_columns_head');
add_action('manage_posts_custom_column', 'cptbc_columns_content', 10, 2);

to

add_filter('manage_cptbc_posts_columns', 'cptbc_columns_head');
add_action('manage_cptbc_posts_custom_column', 'cptbc_columns_content', 10, 2);
