Confine Mouse to Window?

[Mushuukyou]

Some of us play borderless and also have multiple monitors. I didn't find the setting to confine the mouse movement to the game. Is this being added soon?

Edit to add: Can we also turn off HP bars for our own summoned?

Edit to add#2: Can you have it so that when we are tabbed out, on another monitor, when we come back to the game and left-click to put that mouse in and take control, it doesn't immediately create an action in-game? Have the first left-click just be to enable the in-game mouse and acknowledgement that we are back? Thanks.
