You know the old saying? "If it ain't broke, don't fix it". It wasn't broke, so why'd you fix it?
Bring it back!
Not to mention, now I have to start it manually every time I reboot my PC. Now I have to fix what wasn't broke before.
So now you have two things to restore: add an option to minimize to tray upon clicking the "X", and automatically restart when the computer is rebooted.
