what is the difference between using a tab and using a button(to try to make it looks like the tabs)?
<p>From the UI point of view, those 2 ways can be more less the same.</p>

<p>Is there any real difference?</p>

<p>Because using the <code>Buttons</code> way to implement <code>Tabs</code> really make thing easier, you just simply copy and paste the <code>Buttons</code> on each page to make it looks like a <code>Tab</code>.</p>
