In my old job as a backward engineer (of non digital system) we always used graphs. there was a general feelings that graphs are such strong things, that if somebody couldn't give you a graph supporting his theory, it means that theory is weak, meanwhile, debuggers give you a view only to numbers shown in a watch buffer, exactly as Turbo C showed. the first time my debugger could look at a graph of a variable through time, i found a bug, which meant for me that I was on to something, and i want to bring that capability and more to the debugging world, while keeping all of the old capabilities that have been proved a success.
For the time being i'll target projects that were compiled to windows 64 bit with MSVC as it's what i use. supporting 32 bit means also supporting different calling styles, which should be done, but not on the prototyping step of the project.
A video i recorded showing off the new graph system: https://www.dropbox.com/s/748msaygu7kwkk4/2016-06-30-0052-57.flv?dl=0.
