Bug description

A verified indicator is displayed in the action bar of groups, whose members are all marked as verified. I don't know whether this is expected behaviour. If the indicator for groups is expected behaviour, its placement will have to be adjusted (IMHO).

Steps to reproduce

• Create group
• mark all members as verified
• open group

Actual result: Verified indicator is shown on the second line of the action bar.
Expected result: Verified indicator is not shown at all (maybe because groups don't have SN?) or the indicator is placed in the same line as the group name.

I agree with the point regarding indicator placement.

However, regarding the indicator itself - if all members of the group have been verified, it would be reasonable to display an indicator that the group as a whole is "safe and verified", to differentiate it from a "less trusted" group which may have some unverified contact. Manually keeping track of the verification status of all group members is not that trivial.

It would be great if groups could have a weaker form of verification, valid only within the group, where if A verified B and B verified C, then A considers C as verified. Again, only within the group.

I understand this is not trivial, but I think it's almost impossible to verify all group members for groups containing more than a handful of persons.

@paride this is a kind of web of trust and contrary to Development Ideology:

1. If it's "like PGP," it's wrong. PGP is our guide for what not to do.

@p4nci I know and I don't think it's "like PGP": there are no signatures to maintain, no keyservers, no user interaction required, in the spirit of Signal. But I understand the complexities... or probably I don't, and that's kind of the point.

Since https://github.com/WhisperSystems/Signal-Android/commit/65124fd1f2d459a6e40517bf3f572f68b554a783#diff-212a69ad5972e3fe8a7ee6419400f0b1R105 group member names are displayed in the conversation subtitle. Now the indicator placement looks fine for me:
