Using the "just" word

For some reason, just comes before might, but after the other two. "I could just wring his neck!"
I don't see any real difference in meaning by adding just; it adds a little 'interest' or emphasis at most.

I like that explanation!
You even answered my question, GREAT JOB!

I must say I see it a different way:

I just might is probably weaker than I might. I might just by itself is the strongest of the three, in my experience. Why don't you go and tell him what you think of him? I might just! - suggests you probably will and what you think of him will be pretty ripe.

I just could see out of the window suggests I couldn't see out of anything else

While there are several uses for each, here are a few that come readily to mind.
-- If you're that miserable working here, why don't you quit and find a job somewhere else?
-- I just might do that! / I might just do that! (defiance; threat)
