Interesting idea. However, I would like to use that space to gain screen surface, and I don't really desire any menu/status bars. I hope someone will figure out how to do it

I would really like to have a way to do this, did you find anything?

@LvcasX1 thanks for helping with this :) I hope someone will know the answer, this bug is destroying my focus

@LvcasX1 thanks for the tip! now I can see the option. However that's not really answering the question, I would like preview to just open where I am working, not in a fixed place. If for instance I was working on the laptop monitor I would want it to open there

@LvcasX1 my primary screen is the laptop one (the menu bar is there in the settings)

@Tetsujin by 'space' you mean desktop? If yes, I said it in the post, there are 2 desktops, desktop 1 is on the laptop, desktop 2 is on the external screen

@Tetsujin I have edited the post to show a screenshot

@Tetsujin The behavior is the same wheter preview is already open or not. Weird I don't have 'assign to' in the options list in the dock ( I have 'keep in dock', 'open at login', 'show in finder', none checked)
