I tried this and it functions. However at 0.b03 there really isn't any functionality on offer, that isn't available for free from reference tables on the internet for RAL.
If it was possible to use OS X's built-in colour picker for example, then it might change the situation.
There are some really functional and good value shareware applications available for $10 - at 0.b03 and with these limited features - I can't see it being worth $10.
I can't see why a conversion table lookup needs to be 1.8Mb either.
