It may be my fatigue is getting the better of me, but I'm planning to attempt a number of enhancements to the modules page. A combination module of Quick Admin Modules, Contrib Toggle as well as something of my own thinking from reading various related issue queues.
First have a button to quickly toggle the maintenance mode of the website. If maintenance mode is active, then display a button as contrib toggle is meant to do. Have the contrib toggle button always check the database for a variable set, if there is one (presumably with the modules it deactivated when used), deactivate the maintenance mode button (unless a checkbox is ticked maybe to toggle the contrib toggle buttons functions prior?)
On thinking it over, while typing out the above, perhaps these should just be checkboxes possibly underneath the save button on the modules admin form, to save potential page loads, which is the main purpose of this module. I may be looking into the Views-3.x code to see how they are doing the buttons with multiple functions in their views_ui and incorperate that. Right now this is just an idea.

Ultimately, I hope to get this into the Util module.
