I think in fairness there are allready good software programmes on the market from the hard to use WinOLS too the easy to use interface of CMD.
Race is good and has many features if you know how to use them but like most things, its trial and error.
I am happy with Race and CMD, the interfaces are good and practical but they dont show enough maps with many maps hidden away wether it be due too the programmers not looking deeply enough or wether they feel these maps are less important (which i find is not always the case)

Having said that, i think making an interface too easy to use is a bad thing, it would allow any tom dick and harry to get into this line of work without knowing what they are doing (of course you could get the smart alec who says that about me )

If i had to give a good answer it would be to have the power of WinOLS with the ease of use of CMD.
