I've just had a look at your screenshots and I think that is a fantastic project! What a wonderful idea. :-) I've often found that manipulating complicated expression is not tractable because the manipulations take too long. I inevitably end up extracting subexpressions by hand, manipulating them and resubstituting them, e.g. guided simplification. A tool like this could be very useful. The main problem will probably be in remembering the sequence of manipulations which are required to achieve the desired result. If you alter some initial parameters in a symbolic calculation then the intermediate results could be completely different, of course, in which case you'll need fuzzy subexpression matching to make any headway. -- Dr Jon D Harrop, Flying Frog Consultancy http://www.ffconsultancy.com
