Any plans to remedy this, so it works like on Xbox 360?

Currently when I try to use the "Find Race" option with another player in the party - which only works with the controller or keyboard as the menu is greyed out and doesn't respond to mouse clicks - it just queues me solo while the other person doesn't get any notice or similar on his screen.

Also something to consider:
Please add an indication to the task bar when riders joined your lobby during "Searching for players..." so you can tab out and do other stuff in the meantime.
Iirc Rift had this nice feature that flashed the task of the game .exe red(or was it orange?) if your queue for a war front/RvR/dungeon was ready.
That or give us the option to leave the game sound on when the game loses focus, so we can hear the sound effect playing when a player connects to your lobby.

Last but not least:
What does
<GPU antialiansing="0"/>
set to 1 in the conf_graphic.xml do?

It certainly isn't controlling FXAA (which is <PostEffect fxaa="1" ssao_intensity="50" ssao_sampleradius="40"/>.
And yeah, anti aliasing seems to be spelled wrong in the file.
