Following should be in the lite version also [if not already in pro then pro too]

Message Delete [Ability to delete messages]
Archive [Ability too see and search old messages]
User Mute [Ability to mute but user can still see chat]

BBcode support [Really should be a basic I would think]
Message Characters [Character Amount Setting]
