Is there a way to put in time estimates? GTD recommends using these.
There may be moments where I have a bit of spare time and I’d like to make use of it. While not central, I might find time estimates useful to narrow down what’s available to me. This is especially great for actions that take an hour or less because I can say, “Okay, I have 30 minutes” and see all the actions that can be accomplished in 30 minutes or less.
