2. Users should be able to create "Rules" which manage which new conversation is saved in which folder.
For example (if sender == 'foo' => move to folder xyz, if title != 'help' => move to folder xyz, if sender is a follower => move to ...)
there are many possible rules^^
3. Users should be able to create 1 conversation and add x recivers, BUT without having only 1 conversation with all recivers. Instead there should be x conversations. ( so the user doesn't need to copy his text and start x seperate conversations )
If you don't know what i mean, check ipb3^^ AFAIK it's there available.
