Preferences > Profile > Window > Style: "No Title Bar"

Mirroring my sibling comment here, but thanks for the detailed note on how to get rid of the bright white title bar :)

As far as resizing goes, I would suggest using one of the many pseudo tiling window managers available on mac. I strongly recommend spectacle [1]
