Hello!

Best way to edit captions of pages is to do it via Studio->Pages area app. There you may change titles in many of them. Regarding your question - well, design UNA was made to use pages in one style. So if you don't want to have toolbar you may remove from template/_sub_header.html file the following code

<div id="bx-menu-main-bar-wrapper">
<div id="bx-menu-main-bar" class="bx-def-color-bg-sec">
<div class="bx-def-centered bx-def-padding-sec-leftright bx-def-box-sizing">

<bx_injection:injection_top_menu_before />

<bx_menu:sys_site_submenu />

<bx_injection:injection_top_menu_after />

</div>
</div>
</div>

totally or some items from there. Or apply CSS rules to hide them.

With the best regards, Leonid
