Hello,

To remove the woocommerce shopping cart icon, either uninstall woocommerce plugin(if you do not use it) or add this code into your custom css box:
.header_tools .cart {display: none;}
2-To open header button in new tab, go to file functions-tower.php and find these lines:

<!-- Header Button -->
<a href="<?php echo esc_attr($cl_redata['header_button_link']) ?>" class="btn-bt <?php echo esc_attr($cl_redata['overall_button_style'][0]) ?> header_button"><?php echo esc_attr($cl_redata['header_button']) ?></a> 
<!-- End Header Button -->

Replace with these:

<!-- Header Button -->
<a href="<?php echo esc_attr($cl_redata['header_button_link']) ?>" target="_blank" class="btn-bt <?php echo esc_attr($cl_redata['overall_button_style'][0]) ?> header_button"><?php echo esc_attr($cl_redata['header_button']) ?></a> 
<!-- End Header Button -->

Best regards!

Hello,

For that, please add this code into your custom css box:

a.btn-bt.default.header_button {
    margin-top: -20px;
}

Best regards!
