Userscripts.org

hi!
first off, thank you for the script, it's short, yet so massively useful for reading off the web.

i'm new to userscripts, also i don't really want to get into it, so here's my question:
is there a way, to modify the method of opening articles(as below) to run only for the first 20 or so items, and on the same idea, rather than marking all as read, mark only the first 20 read.

this part, un-modified from your script:
// Open in tabs
$(selector).each(function(index, domElement){
window.open($(domElement).attr('href'));
});

// Mark as read
oau_fireClick('mark-all-as-read');
}

mark
