Think about what you think would work better for you, or try out different things. You might want to keep all your computer actions on one list. You might want to divide them up by roles, if you like doing several actions for one role one after another rather than jumping around. Or, you might want to divide them up in some other way, such as type of action: you might prefer to do several emails one after another, even if they're for different roles; or you might prefer to do several quick actions one after another sometimes and at other times work on things that take longer, so you could divide them up by length of time they take. Maybe you prefer to do some types of work in the morning and different types in the afternoon. You could divide them up by how difficult they are or whether they're more pensive or more of an interaction with the computer.

I like to keep my actions sorted by priority and by the amount of time-and-effort they'll take. That way I can do the higher-priority actions first without having to read the whole list every time; I can get the more difficult things done first when I have a normal level of energy; and I can choose easy things when tired without wearing myself out by even contemplating the more difficult ones.
