 	It's only a proof of concept so far : there are many many ways this could be enhanced (suggestions and patches are welcome : the source code is on <a href="https://github.com/mossroy/evopedia-html5">github</a>). In particular :
 	<ul>
 	<li>The performance should be optimized when reading an article</li>
-	<li>Searches are not always very accurate</li>
-	<li>The links inside an article do not work well</li>

 	<li>On a real device (with small memory) and a normal dump, reading an article crashes because it loads too many things in memory</li>
 	<li>It is hardly usable on a device because the buttons and inputs are too small</li>
