Alright, so after Hela finishes murdering Asgard she goes to the vault. When she looks through, she doesn't seem to care about most of it. Altough she does say the tesseract is ok. But once she finds out the Bifrost key sword thing is gone, why doesn't she just use the tesseract to travel. It seems easy. Not to mention the fact that it can be used for weapons as well. So my question is. Is there any reason for her not using it or picking it up?

She's a warrior caste, not an engineer/smith caste.  Even Loki needed human scientists to set up the portal.

Could the Tesseract do it? Yeah.
Could Hela make the Tesseract do it? Probably not, at least without some of the asguardian smiths doing the legwork for her.
