I&#x27;ll use an example that has been confusing for me. The contact list alternately shows some people in gray text and others in  black while having a separate phone icon.<p>1) It was not immediately obvious to me that I have to select the name to msg. iMessage deals with this by having a specific messaging icon that makes it clear.<p>2) I was able to guess that the grayed out names meant no messaging but then again I tried to call multiple of these contacts and it does not seem to work properly in that that I can&#x27;t seem to reach those people. Not sure if this is broken... Part of this is the legacy of Redphone&#x2F;Textsecure so as Signal spreads as a single app across platforms, I&#x27;m hoping this issue somewhat goes away. [1]<p>3) It would certainly be nice to have the whole contact list be visible instead of just the known contacts with Signal&#x2F;Textsecure&#x2F;Redphone along with the ability to easily share an invite to others to use Signal via iMessage, email etc. (use the standard iOS share dialog) I&#x27;m willing to bet this gets a lot more people to see&#x2F;use&#x2F;invite others.<p>4) I would argue that groups&#x2F;multi-device is the same abstraction in this case (each device would be a hidden subcontact) hence it should be possible to get multi-device support in short order if group support is already there.<p>I don&#x27;t believe any of the things I&#x27;ve listed above have security implications but I could always be wrong. Maybe I&#x27;ll file some tickets this weekend if I have some time.<p>I did some digging and found the link below. Requiring people to understand and handle an issue around a bloom filter is a bit much. That part should just work.<p>[1] <a href="http:&#x2F;&#x2F;support.whispersystems.org&#x2F;hc&#x2F;en-us&#x2F;articles&#x2F;212743488-Why-are-my-contacts-different-colors-in-my-contact-list-" rel="nofollow">http:&#x2F;&#x2F;support.whispersystems.org&#x2F;hc&#x2F;en-us&#x2F;articles&#x2F;21274348...</a>
