Hi all,

This is an add-on to GOG that improves usability and adds functionality.

What it does
- shows game title in green with a big check mark if you own it.
- adds links to search for the game on YouTube, Steam and metacritic

I got tired of purchasing games I already own, happened once and took a lifetime to get a refund.
I also need more places to check reviews. GOG reviews are not useful because they are biased to be very positive by design (pm if you wanna know more - won't complain here).

So I came up with my independent solution.
You need a css/js injector for this to work e.g. https://goo.gl/SJWKyv

Attached images show before and after, below is the css and js code you need.

I find this especially helpful during sales.Enjoy!

gog.css
======
.header__title,.inj-quick-links {
display:inline-block;
}

.inj-quick-links a {
padding:0 0 0 15px;
font-size: 14px;
}

.inj-quick-links a:hover {
text-decoration:underline;
}

.owned {
color: rgb(55, 87, 1);
xborder-bottom: 1px dotted;
position:relative;
}

.owned:before {
content: " ";
display: block;
border: solid 0.4em rgba(55,87,1,0.9);
border-radius: 50%;
height: 0;
width: 0;
position: absolute;
left: -0.95em;
top: 50%;
margin-top: -0.35em;
}

.owned:after {
content: " ";
display: block;
width: 0.15em;
height: 0.35em;
border: solid rgba(255, 255, 255, 0.9);
border-width: 0 0.12em 0.12em 0;
position: absolute;
left: -0.7em;
top: 50%;
margin-top: -0.225em;
transform: rotate(45deg);
}

gog.js
=====
// wrap in function - runs when page is ready - same as calling Handler for .ready()
$(function() {

// quick toggle - replace with true to disable script
if (!true) return;

function main(){

// block execution until element is available
$element = $('.header__title');
if (!$element.length) {
setTimeout(main,500);
return;
};

// main
colorOwned($element);
var title = ' ' + $element.html().toLowerCase();

var queryHead = "https://duckduckgo.com/?q=\\";
var queryTail = "";

var youtubeURL = encodeURI(queryHead+'youtube pc gameplay'+title+queryTail);
var steamURL = encodeURI(queryHead+'steampowered'+title+queryTail);
var metacriticURL = encodeURI(queryHead+'metacritic pc game'+title+queryTail);

var youtubeHTML = '<span><a href="'+youtubeURL+'">Youtube</a></span>';
var steamHTML = '<span><a href="'+steamURL+'">Steam</a></span>';
var metacriticHTML = '<span><a href="'+metacriticURL+'">MetaCritic</a></span>';
var containerHTML = '<div class="inj-quick-links">'+youtubeHTML + steamHTML + metacriticHTML+'</div>';

$object = $('<div/>').html(containerHTML).contents();
$element.after($object);

}

function colorOwned($e){
if ($('*[ng-show="productStatus.isOwned"]').is(":visible")) {
$e.addClass('owned');
};
}

// delay exectuion to wait for page JS to finish
var delayTime = 0;
setTimeout(function(){main();}, delayTime);
});

Maybe I should have written a better post title. Still hope somebody finds it useful.
