This could be certainly useful. I would not put the operation sequence to the title but to some new kind of metainformation (log). AFAICT it can't be done automagically, without adding explicit support to each data processing module, because the data flow is not derivable from outside. But it can be probably be done so that the amount of code required in modules to support this is pretty minimal – a couple of lines per module. At least if we keep the chain linear and give up on representation of Arithmetic or Mark With. And solve the interaction with undo. The log can then include also the current module parameters (essentially a subset of ~/.gwyddion/settings). I suspect the next request would be to make these logs replayable though, and this way lies peril. I can imagine about three hundred ways it will break if we ever try to implement it... Some people took this concept to the extreme and generally always try to keep input data and to reply the operations (see e.g. GEGL and non-destructive editing) but this requires a different approach to, well, pretty much everything.
