GTD separates 2 modes: I like to call them "Management mode" and "working mode". In the first I am processing my inbox, reviewing, looking at projects, describing tasks and planning my work. In "working mode" I am actually checking off tasks.

Working on tasks is something I do in a certain context. That way, I should not see things that are not yet available (focus tomorrow, Scheduled, someday or waiting). Because what would be the use of making a task "someday", when it shows up right now?

If this is behavior on purpose it would be nice to make this a setting, so that I can only look at my work that can be done today/next.
