So, when you first input a DC item, you can add comments or expand on the idea.
I know the idea is to dump the idea in the DC and forget about it.
But often, it's necessary to put much more info down when an idea comes, for two reasons.
1. A one-line title may not be enough to remember the full scope of the idea.
2. When ideas come, the creative juices might already be flowing enough that a single line will not be enough to record the outpouring.
