Use Forward and backward arrows to navigate through open tabs. It is useful to check subs when there are a lot of them. At the moment they have no function when each sub is open in a different tab. They only work when subs open at the same tab.
I would also like to see the name of the sequence in the title bar since I am always running two SGP instances, one for each of my two scopes. Hopefully there is some other way to display the entire image name.
