Great app which needs some improvement

That is a great app and thanks a lot for the developer.
I recently started using it and here are the issues i see for mobile;
– On mobile (android and ios) sound effect is not working,
– You can’t understand if someone is asking you to join a private chat, it is just written in main chat area, no option to click and start it from the message, you need to go and find that person nick on top menu.
– In mobile hard to see the first message as windows goes up a lot,
– close and hide buttons are too close to each other, could be great if they were more apart.
– In desktop and mobile there is no send button, you need to press enter…could be great if there was a send button,
– you can’t send images
The rest is great,
Thanks again to deveoper
