Lobby Chat Mode Switching & Invitation Blocking

Anyone else find these annoying?

While in the Lobby, you type out a message intended for your clan and then realise you haven't change the mode from 'regular' to 'clan', so you change it to clan and then you have to type the whole message again because it's gone! Why can't the message stay there? Grr!

Also, in the settings you can select to block invitations to rooms as this always gets in the way when trying to chat to people. But what if you want to have invitations available from friends or clan members?
Could we also have an option to block invitations from everyone except friends and/or clan members?
This would work alot better than having to keep changing the settings every time you want to chat.
