gksudo doesn't support persistent sessions - normally the sudo command retains the privilege granted as a session which lasts 5 minutes or so. gksudo doesn't feature this, and requires the user to enter a password each time. While using gnome 3 (via ubuntu gnome), I have seen some programs which prompt the need for a password in a more modern, gnome-3 style, while having the behavior I described in sudo above. What is this program, or a program which has the features I require? Specifically - a GUI for sudo which retains the privileged session for some timeout.

There is no replacement; Graphical applications are not designed to and should not be ran as a different user. If an application requires root privileges it should be designed as multiple processes where a small minimal process can be elevated.

You would use Polkit at that point to launch the new process as root though.

Since gksudo and similar are now deprecated, pkexec might be an option if your system includes it.

So, instead of 

sudo dolphin

Try 

pkexec dolphin

You may have to configure the policy for dolphin to allow GUI usage as described here: https://unix.stackexchange.com/questions/203136/how-do-i-run-gui-applications-as-root-by-using-pkexec
