When and where can you suggest a borderless windowed mode?

I am unsure if this has been posted before. I searched, and found nothing - probably, I didn't search enough.
But I really want to know, are we even getting a borderless windowed mode? I don't want to have to make a 5 steps manipulation to play in that mode, and the only windowed mode we are allowed has the huge white borders, it simply looks ugly. The reason I want that borderless windowed mode is because I play with two monitors, and I gotta admit that the game closing when I switch my cursor to the other monitor is plain annoying.

Thank you for replying anyway!

Right click Rimworld in steam, edit launch options, type "-popupwindow" without quotes, launch Rimworld, go to options, disable fullscreen. DONE.

Is that too many steps?
