Add Option to have Window Buttons plugin show the Application Name when ungrouped

Currently, if "Group windows by application" is checked, the grouped lists will display the Application name, but any ungrouped items will show the window name. An option to force ungrouped items on the window button list to show the application name instead of the window name would be appreciated. I feel the majority of users don't need to have what the title of the Firefox page they are on in the window list, for example, but would prefer to know that button is Firefox.
