Basically I just don't want to click 1000 times for each system I have.
At the moment you only have Right click then left click add favorites to list. So that's 2 clicks + 1 click to go to the multi system tab. + 1 more click to save xml (not implemented)
You can have the extra 1 click to save this favorites to whatever you like.xml or generate the whole lot in 1 click. So all in all that's 4 clicks per system.
