$tabs = array( '1' => 'Layout 1', '2' => 'Layout 2','3' => 'Layout 3','4' => 'Layout 4','0' => 'Main Options');
CHANGE for the new line:
$tabs = array( '1' => 'Layout 1', '2' => 'Layout 2','3' => 'Layout 3','4' => 'Layout 4','5' => 'Layout 5','0' => 'Main Options');
This line is responsible to add more tabs/layouts, just add ‘5’ => ‘Layout 5’, as above, to add new tab.

register_setting( 'slc_options_4', 'slc_options_4', 'slc_options_validate' );
Now INSERT the new line:
register_setting( 'slc_options_5', 'slc_options_5', 'slc_options_validate' );
4.Search for the line:
if ($tab <= 4 or $gvext == 1){
CHANGE for the new line:
if ($tab <= 5 or $gvext == 1){
Your 5th layout is ready to use, if you need more tabs, repeat the process. Thanks for the developer of this plugin, it’s amazing!!
