Conky currently has a goto(x), but no corresponding goto(y) to align text vertically. A single goto(x,y) or a goto(y) would help minimize the use of voffset, which is prone to break layouts when fonts change.

Edit: I have got a working(?) version of this gotoy(), by just copying the code for goto(), and updating cur_y. I do not know how correct it is. If anyone is interested, have a look at easysid@f6ef58a
