Move and/or have the option to hide the button on the toolbar. It is very much out of place right now.

I recommend the status bar icon theme, but since the menu only has one item, not even that is required.

If you mean SeaMonkey toolbar button, you can hide it on preferences window:

1. Open Preferences window;
2. Click on Navigator panel;
3. Uncheck Script Manager on Navigation Toolbar groupbox.
