[MCU] What sort of abilities does the Soul Stone give you?

Alright, long story short I spent several years of my life looking for the Soul Stone, eventually I was able to find it but to actually get it I needed to sacrifice the person I love the most.

I did all that, and the soul stone is mine to use.

But what exactly can I do with it? I mean what sort of abilities does it have?

Thanos used it to target Strange's soul to find the real Dr. strange when he did that spell that cloned him. Afterwards he uses it to push Strange's astral form out of his body but Strange puts himself back together quite quickly. It was also used to target the souls when snapping people out of existence/back into existence.

Edit: Joe Russo answered this question during their Collider interview; 

>“The Soul Stone obviously has the ability to manipulate your soul, the essence of who you are. One key moment where it’s used is where Doctor Strange turns into multiple Stranges and then Thanos uses the Soul Stone to eradicate all the fake Stranges and momentarily shoves Strange out of his own body, and Strange has to pull himself back in... Of course when Thanos goes to the Soul Stone itself, to speak to his dead daughter, he obviously has an ability to resurrect, conjure the spiritual representation of the people who are dead."
