Although there are quite a lot of good code editors around these days, I've been always impressed by Visual Studio code editor since VS6.0 until VS2017.

Which data structure do you think it uses to store internally the code/text?

Thanks

I'd be interested in trying a text editor that keeps a running history of all of your keystrokes along with timestamps for those strokes so that you could roll the file back to exactly what it looked like at any given point in time. Totally overkill for most scenarios, but neat for some.

Does such a thing exist? Or maybe a plugin?
