Hi Mo, also maybe instead of looking at the URL it may be better to look for that global variable existing.

Something like this:

    var uipanels = moi.ui.getUIPanels();

    for ( var i = 0; i < uipanels.length; ++i )
    {
        var uipanel = uipanels.item(i);
        
        /* uipanel is the HTML window object that holds global variables. */
        /* Find the one that has a global variable "LiteGraph". */
        if ( uipanel.LiteGraph )
        {
              moi.ui.alert( 'found it' );
        }
    }
