This is a really simple plugin that offers a single command for moving to the previous buffer (window/file etc) you were viewing. This should is similar to how the <c-^> or :buffer# command works in VIM. This is something that most VIM users use all the time (and probably have mapped to a better key like shift+tab). The workflow is similar to this:

I am editing a file A to add something. Then I press ctrl+p to jump to another file B to use what I just added. Then (of course) I forget what I did on file A so I quickly switch back to A to take a peek at what I did there and immediately switch back to B to once again do the change. The after a while I will need take a peek again to A, etc. Using this you should be able to do that very quickly.

Notice that I used the "buffer" word to make the connection with VIM :)

You will need to add a keyboard shortcut to execute the goto-previous-buffer command. I recommend assigning it to shift+tab or ctrl-shift+tab (I know that these keyboards are already assigned to move the indentation left or cycle to the other open buffers but I use that thing all the time so I recommend assigning it to an easy combination). You can also use ctrl+6 like vim! To do that press ctrl+shift+p and then search for open keyboard shortcuts. In the filter in this write goto-previous-buffer and then click the cross or pencil to change the shortcut to your desired one.

Example JSON keybindings configuration:

[
    {
        "key": "shift+tab",
        "command": "goto-previous-buffer.goto-previous-buffer",
    }
]

None that I know of. This probably won't work when the previous thing you visited was not a real file :)
