The beers are on their way, donated some bucks
Also, 2 suggestions i will like to expose, wish you consider it:

1- Can you align the text, to the right for me and to the left for the receivers in the conversation screen, instead to both to the left? forget about the bubbles, i know you dont like it, but what about this?

2- Maybe separate the open conversations (or the contacts who already talked with) in one screen, and swipe right to the "All Contacts list" like in Wazapp? I´m used to this. Or at least put a big separation line :Open conversations - Contact list with no conversations yet.

Thank you for your work and happy New Year's Eve!
