Richard - can I suggest a couple of additions to your users 'wish list' for the next big update:-

1) Comment field [say 200 chars long] for each node so users can make notes etc to help checking, data verification, record assumptions etc.

2) Some sort of programming interface [like excel VBA or AutoCad AutoLISP] so users can write macros to do manual calcs within Caesar, based on the raw data Caesar produces

3) [this ties in (1) & (2)] Auxiliary user defined datafields - say 3 x text & 3 x number formats

If you're not sure what I'm getting at with (2) & (3) let me know and I'll post some psuedo-code showing what I'm thinking of
