I just bought the wordpress chat from here and it

Hello, I just bought the wordpress chat from here and it is running nice, but also facing some tiny problems
1) Buddypress local avatars are not appearing in the chat, I mean if any member of my site is not having any gravatar account/image then his/her avatar will be empty in the chat? is it possible to display local avatars?
2) There is the option for moderators or admins to delete chat messages, but a kick/ban option will be great for this plugin, considering that a member is disturbing others in the chat, instead of deleting the user from dashboard entirely, some temporary kick/ban will be a great option.
3) Is it possible to add custom smileys?
