There's no such feature in GIMP yet. The request for it has been tracked for a long time, but so far noone volunteered to implement it.

The same results as the History Brush can be obtained by working on layers within an image in the GIMP. Basically:

1) Duplicate the layer you are about to do things to, or in the Layers dock do "New from visible" to get a layer that includes the result of previous layers combined.

2) Do things to your new layer.

3) In the Layers dock dialog, do "add layer mask", accept the default setting - a white mask that leaves all parts of the image layer visible.

4) Paint (or fill selections) on the mask layer in black, to "undo" the changes to parts of your new layer. To leave the changes in your new layer partially visible, paint or fill with shades of gray; to do this progressively, i.e. blend edges etc., set the brush tool's opacity to some value less than 100%. Then, additional strokes will progressively darken the area of the mask you are painting, progressively revealing the layer(s) below the one you are working on.

Different tools, different workflow, same result.

It may seem odd but you would probably need to explain what a history brush is, and how you use it, and what you're trying to solve. The GIMP developers are not in general Adobe PhotoShop™ users.

It is a simple way to "paint" away one layer to reveal the one below. EG. I duplicated one layer then desaturated it. I then took a snapshot of that layer.
I then used the History Brush to paint over certain sections to reveal the original coloured layer beneath.

Sounds to me like you want Layer Masks? Take a look at this tutorial on the website and see if it offers what you are looking for:

Achieves the same thing I think. Different tools for the same result. I'm getting to like Gimp!

There's a lot to like. If you do a lot of "painting" of various sorts, being able to change the size and hardness of your brush via the mouse wheel might be one of them. This is not configured by default, but the menu where this can be set up is shown here:

I find alt plus mouse wheel up or down to increase or decrease brush radius, and ctrl-alt plus mouse wheel to increase or decrease hardness convenient. Your mileage may vary. Whatever keys you use, it sure beats constantly switching brushes on detail work...

My own admittedly quirky way of setting up the Gimp is shown here: http://pilobilus.net/gimp_tutorial.html
