Is your feature request related to a problem? Please describe.
Yes. Currently i'm not able to create a massage to multiple contacts.
After choosing the first contact (the app will enter the chat history of that contact, which does not make much sense if i'm planing to create a group chat), and then start adding other contacts (by typing it, instead of scrolling thru the list - which i also think is not ideal) when i press the accept button the app returns an error and does not create the desired group message.

Describe the solution you'd like
When we start up the app and after we go to the Plus Button to create a new chat/message we get to a list of contacts.
In this list of contacts we should be able to:

long press a contact to enter "selection mode" and be able to select multiple contacts

in order to create a group message.

Describe alternatives you've considered
there's no any good FOSS alternative that deals well with group messages that i know of. Only proprietary apps (i don't trust).

Ok... sorry about that!!! :p

I do not have any crash report... it just throws a popup message saying that an unknown error occurred.
I can reproduce the bug, however! :)

That's enough :) If you could create a new bug report and describe the steps, we can take a look into it.
