I use an action support regularly. For example, when I hope in my car to run errands, it may contain a prescription I'm going to fill, coupons for a store I'm going to visit, letters I'm going to mail, etc.)

I do not like "tossing it into my briefcase" as a way to find the material when needed. I likewise do not just toss them onto the seat of my car or carry them, as either approach has too many risks for me.
