[Sugar-devel] [Feature] Start an activity from another activity

[James Cameron]

I have no use case for the feature, sorry.  The activities I'm mostly
concerned with stand alone.

But if an activity is written to use the feature, a dependency is
created; my question is _will_ it be encoded, and what are the effects
on other actions that change the list of activities?

What you describe as non-essential is a type of dependency.  Do you
have a use case for that?
