How can the data density be improved? [OmniFocus 2.3 added custom columns layout]

Another moderator brought this thread to my attention. After some discussion, we feel like “when are you going to do thing_x” isn’t generally a different enough topic to warrant a new topic if one about that thing already exists.

In other words, I’m going to merge this thread with the existing Data Density one. (If you’re reading this post now, it’s in the thread I moved it to.)
