hi guys I would like to get some support from the tools to help us curiving out etoys. Here is the scenario: when I see a method I would like to see a color or symbol which tell me how many sender kinds were calling this method either statically or dynamically. I would like to put etoy classes in red and see the colors propagating in the system. So we could get a kind of coloring schema. We could do the same with letters then we could have some single colored methods or mix Alex/Damien do you want to help because this could be fun? Then when i see how I work I always do a kind of yoyo between senders and implementers it would be really interesting to log the senders and implementers so that we could trace back the sequence and understand also how the remove happen and the frequency of the removal.
