Theme-Settings not fully dynamical
At the Moment, the Logo for the Backend-Theme is hard-coded in File config.inc.php:
$conf['logo'] = 'themes/default/images/header_logo.png'; Here is a dynamic Piece of Code needed, which show the logo depending on the actually choosed Theme:
$conf['logo'] = 'themes/'.$conf['theme'].'/images/header_logo.png';
In this way, you only need to change one ($conf['theme']) variable to switch the whole theme.
BTW, would be great, if APP-Title (in config.inc.php as constant:ISPC_APP_TITLE) are also editable bei BE-GUI
