Items rendered out of window viewport

On a full-featured Drupal site with many modules installed, menu items below Site Configuration are displayed below the window viewport. Admin must have a mouse wheel to access items at the bottom.

How could we solve this issue?

1. Counting items, reallocating them into more than one parent item?
2. Do spicy CSS tricks to let them extend to the right?
3. Include a nifty JavaScript to measure the viewport and conditionally re-arrange them?
4. Your suggestion?

I have a mouse wheel. ;) So I might not fix this without sufficient demand.
