Now that I've used OF for a while, I'm even more convinced I want to be able to apply background colors with a single keypress. That would solve so many problems with one feature!

I could use different background colors for the following things which currently cannot be expressed, and are in fact orthogonal to what can currently be expressed:

- "waiting for" actions -- something I can't act on until I hear from someone

- "not on weekend" actions -- things I'm willing to work on Mo-Fr, but not Sa-Su

- quick actions -- faster than entering something in the duration column, and it would save me from using that column

- on-hold actions

Other people could use this for their own needs. It's a one-stop substitute for colored flags or tags. It would be great as a visual aid, but it should also allow sorting and filtering.

OF is great, but it's rigid. This feature adds flexibility at no cost to those people who think OF is perfect as it is: they don't have to use it.
