On the admin screen everything is displayed in tables. But the problem is that some url's are quiete large so the table's are really big and go out of the screen in 1024*768.
Not sure what you want here -- if its a clickable url then hide the url and give a short title.
Two other problems: the links to the noclicker don't apear in the menu bar and the admin block.
You need to implement the functions:
plugin_getmenuitems_noclicker()
and
plugin_getadminoption_noclicker()
in your functions.inc
