With LCARS 7.1 and above you can add buttons to the LCARS sidebar. Here's how: in your HTML page, locate the DIV with the class name "panel-3" and insert the following code after (shown in red)...
<div class="panel-3">03<span class="hop">-111968</span></div>
<a href="url">button 01</a>
<a href="url">button 02</a>
<div class="panel-4">04<span class="hop">-041969</span></div>
NOTE: You can insert as many buttons as you like, but do so only between DIVs "panel-3" and "panel-4" for best results. Also try and limit the amount of text for each button to no more than approximately 8 characters as they may not all display when viewing on smart phones.

There is a unique ID tag to shorten the height of *panel-3" so the sidebar buttons don't start so far down the LCARS sidebar. See Info-Graphic 02 for instructions.
