Hi @smexhy,
I hope you’re well today and thanks for posting! Really appreciate your patience with this too, let’s get this all sorted out for you! ??
I’m not seeing any issues when using both the corner chat and a page chat in testing over here. Given some of the other items you mentioned, I suspect there might be some sort of conflict. Could you try deactivating other plugins and switch to Twenty Fifteen theme to see how it works then?
Similarly, the emoticons and avatars (for public users) work just fine on my end. Perhaps the plugin/theme check above will help get to the issue behind that?
As for resizing, that actually depends on your theme. If your theme’s content area adjusts to resizes then the plugin should. At least it does for me with Twenty Twelve, for example.
The email requirement is actually built into the plugin as a way to try and avoid duplicate users so to change that would require a bit of an extensive change of the plugin code like noted here:

I hope that helps and if you could let us know how that theme/plugin check goes, we’ll gladly see how we can assist. ??
Thanks,
David
