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

[James Cameron]

Thanks.

What you describe sounds like activating a journal entry, which causes
the default activity to be started.

I think I'd like to hear from activity authors who would use the
feature.

For example, download completion in Browse; at the moment it offers
"show in journal", but could be "open".

Dependencies are still a concern though; how should Sugar react if
there is no activity capable of opening an object of an unusual mime
type?
