I'm pretty sure we have a feature request open on showing action group names in context view in some fashion: emailing the
support ninjas and let the team know you'd like to see that happen.
In the meantime, I'd recommend making action names understandable/actionable on an individual basis as much as possible. Using a random example from earlier in the thread, "Email Brian L and Jane to find mystery developer" is a similar amount of typing to the nested pair of actions, but is more understandable when viewed later in context view.
Does that help at all? You lose a bit of flexibility since you can't check the emails off individually, but overall, it seems better than the current situation. :-)
