Hi,
I've just started using Omnifocus and so far I'm very impressed. One thing that has me a bit confused is that in my library I have icons for both "Miscellaneous " and "Single-Action List". What's the difference? And why do they both have an icon that looks like a file box, as opposed to the icon that the projects have? Does the difference in icon indicate any difference in functionality?

Many thanks in advance,
Abe Z.
