Having an "Apply" button would be great to avoid closing and reopening menus when trying things out.
Renaming the OK button wouldn't really be needed as a lot of application already use it as a "Save and close"action, with an Apply button next to it.

If you add the "Apply" button, you'll probably have to rename "OK" to "Apply and close" to avoid confusion.
