Memory Access Highlighting?

[Eoin-ONeill-Yokai]

On Mesen-S and some other debugger tools, there's the ability for highlight recent writes / reads or executes as a color that fades over time. This is useful in some circumstances where you need to pinpoint changes to values in memory synchronized to actions in game.

Any chance that this feature already exists and, if not, would it be difficult to add it? I could even contribute a bit myself if I have an idea of where to look in the debugger. (Relatively new to working on things such as debugging tools.) Would it be enough to use Qt to simply track changes to the table and animate the color that way?
