On top of Hex not having a tooltip to display the stat that will be hexed, Find Familar doesn't display a tooltip to show what kind of familar would be summoned (although unlike Hex you can kind of guess based off the icon but having a tooltip would be better).
Also from watching a streamer go through the game on the PC version, during dialogs where one or more of the options uses a skill (Persuasion, Deception, Intemidation, etc...), the PC version displays the characters modifier for that skill when they hover over it (e.g. Deception +/-N) allowing them to pick the option with better odds, I don't see a way to do this on the Stadia version.
