Feature description

In a group conversation, presently the only way the program distinguishes between participants is the icon/letter to the left of the message. If the participant is not in contacts, this can result in the numeral 1, the symbol +, or whatever else happens to be perceived as the first character of their ID string, becoming the sole identification of the participants. This is entirely unhelpful. Even a single letter, from the contact entry, is not ideal, due to overlap and ambiguity.

Adding the entire ID string in small print is much more helpful. Additionally, using 2, not 1 character is more helpful.

Why do you want this feature?

The present format for group messaging is very vague, and difficult to see who said what.

Additional information

Here's an example from QKSMS, which I dropped in favor of this because it doesn't support many MMS features.

Same conversation in this app. Impossible to tell who said what.

The comparison also illustrates another case where color coding correspondents is helpful, but that's a separate feature request I also made. :)

Thanks @Aga-C for all the work you're doing on the many things I'm posting about this app.
