please add apply_filters and do_action hooks

great plugin and works out of the box!
but please explain how to modify $mess_max_length and $strip_spaces without modifying your plugin file?!
we need some filters here. and please add a do_action hook for adding some custom hashtags by default. i.e. i have a post_type called “cars” and with each post, i want to add “#car” without tagging it each time by hand.
something like this would be nice:
line 92 of publicize-with-hashtags.php add:
do_action("hashtags_append");

then in my functions.php i can write:

function hashtags_append_static(){
	global $mess, $post;
	if(get_post_type() == "cars") return $mess .= ' #cars';
	return;
}
add_action("hashtags_append","hashtags_append_static");
