This is not correct. Read can display text files. If you have any text file
tat can't be opened by Read activity,
send it to me.

No. Because then you need implement in Browse the logic to know what
activity
can open every type of file (sugar-launch need you specify the bundle_id)
Another reason to not do that is sugar-launch is part of sugar, not the
toolkit,
and the activities should use the toolkit code, no sugar code (even when
that is not
always respected)/

Yes. That is the expected behavior. What is confusing?
Sugar configure default activities for mime types where there are more than
one available
(in the file data/mime.defaults)

The logic is not moved to Browse. Is moved to sugar-toolkit-gtk3, where
every activity, and sugar itself
can share the same logic.
