Suggestions for client and gameplay

I got an honestly no joke suggestion for riot, why don't you make a "Logout" button, for example if you want to logout instead of closing the client and having to open it again just logout and leave the client open, because honestly sometimes it takes a while to open. Another suggestion, as a MAC client user I see that there is no smart-cast option for our client only quick-cast with indicator, but I think it does not work the same as smart-cast, it would be nice to have it on mac-client as well.

Hope we are able to get those useful tools for us players. Please Riot.
