Reduce height of Dope Sheet to give more Workspace

The custom view options in 2020.5 are great but I cannot reduce the height of the Dope Sheet to only include the layers I am using, And it therefore takes up 1/3 of the screen. When I am only using 6 layers I would like to have a larger workspace. But the drag parameter only gives me more layers not less. Is there anyway to have a 6 layer project only 6 lines high in the Dope sheet?

Can you increase your screen resolution? 1920x1080 is the lowest we support and is pretty crowded in Mocha.
