Chat problems – submit post and on mobile devices

Hi support team,

I love your easy to use plugin, but have some issues to be solved:

1. text submission failure
sometimes by click on enter to submit text, it does not work. A submit button would be helpful. Screen Shot – http://screencast.com/t/BeBFPHtMIa

2. Not able to choose a member to chat.
The chat link is covered from other plugin (Mobile Share by errnio) Screen Shot – http://screencast.com/t/upnXclPJZwKH

3. How am I able to search for members or only display online members?

4. Setup management within wordpress backend has no settings to be enabled or dis-abled or settings to be changed. Where can I change the color and location of chat buttons.

Looking forward to your help. Regards, Alex
