This is such a simple idea that I'm sure it has already been considered or discussed. When I run CCleaner I often have different tasks in mind, for example, only very occasionally will I perform what I call a "deep clean", and sometimes I might not really want to clear my browser settings but can't be bothered to untick the boxes etc. If CCleaner had different profiles of settings which could be changed from a drop-down box at the top, I think this would be awesome. That way I can choose a profile and know that I haven't accidently left something ticked that I didn't intend to clean.
It would also make it easier to tell friends and family what to do with CCleaner. At the moment I run CCleaner myself on my girlfriend's laptop because she wouldn't know what the things mean. But I could tell her to run the "default" profile if she thinks it's getting slow, or the "deep" profile once every few months and it would make the job easier. It would also make it easier to somehow automate CCleaner to run a particular profile on startup, for example.
Okay, but even with everything ticked (except WFS and Secure delete)it hardly takes more than 5 seconds if you clean on a daily-basis. Most of the time what is cleaned, is useless stuff which you probably wouldn't require anyway. Browser cache and cookies are only removed if the browser is closed.
So, just my opinion that a fast(er) than what is already the current regular mode would make no sense.
I have no doubts that as an advanced user, there are workarounds to garner a similar functionality. However, I do believe that these are, by definition, workarounds, and not suitable for the average user. My suggestion would open up this kind of advanced functionality to the masses, which if we subscribe to the "don't make me think" UI mentality is exactly the kind of innovation that people look for. People want software that Just Works; the average user is intimidated by options, especially when they aren't familiar with the terminology. Some might argue whether ignorant users should use a tool such as CCleaner in the first place, but why should they be excluded from the benefits because of this? In my opinion, CCleaner should ship with new PCs and deserves to be as ubiquitous as Firefox, antivirus or iTunes in terms of the software people choose to install. Why make it more difficult than it needs to be?
