It would be cool to be able to scroll in the script editor with the scroll wheel on the mouse, and maybe mouse3.
Also, speaking of the script editor, highlighting /*...*/ comments as a comment would be nice as well.

Agreed. In my opinion this one's a high priority.
Especially with the scroll bar being so buggy.

Another handy script editor feature would be horizontal scroll bars, for when lines of code go out of the editor.
