Hello,
You can find out which SQL queries are executed if you enable
SQL debugging on your site. That way you can catch every request and use it later in your custom control.
If you want to edit the
CMS Desk/CMS Site manager, you can find out what files are displaying the given content with the Firefox browser. "Right click on the given frame -> This Frame -> View frame info" - there is the path of the file, which contains the displayed page.
However, I would still recommend you to wait for the new version, since if you change the UI it might be overwritten with the next upgrade.
Best regards,
Boris Pocatko
