Dear oded,
I'm sure your intentions are honourable, however, my eye is drawn to your part statement of 'could be VERY EASY to look up'
The whole point of a cryptic clue is that it is a battle between clue compiler (The Setter) to use whatever (learnt) skills to Inveigle misdirection and possibly sinister wordplay to cajole the solver away from the true representation of the clue parts. In turn, it is the solver's goal to use his/her learnt skills to identify what parts are the definition and what is the wordplay and only then can they use their experiences to decipher the relevant pieces to fit into the solved correct answer.
I use many tools to help me do this, including the Chambers dictionary, a good thesaurus, an encyclopdia and a few other books. I also use the internet (Google) for a final 'Go to' for all those very hard to find references.
Although I feel it would be impossible to invent such a reference facility, I think I would pack up my books, take them to the charity shop and never pick up a cryptic crossword again because this new reference facility would destroy the very essence of the cryptic clue and take away the reason we do them.
Our world is full of gadgets and things to make stuff easy.
The cryptic clue is something else, it's crafted from a creative mind and should be savoured and appreciated for what it is, a piece of enigmatic word mastery.
Why not look online and read about how to solve clues and the many different styles of clue and wordplay, then spend some time trying them and asking for help .
I feel you've found what you're looking for with this site, no need for a new reference book or fancy computer programmes. Just ask here, there is a plethora of superb solvers and setters where you'll always find the answers and get explanations.
