Could anyone please give me a hand to split the display vertically to create a third window that spans across the entire frame when there are two pre-existing windows side by side?
I often have an open window, then I do an org-capture to create a todo, but then I'm not sure about the date, so I open the calendar which gets scrunched underneath Window # 1 -- I'd like the calendar to span the length of the frame.
Window # 1 | org-capture window
Then, split screen vertically:
Window # 1 | org-capture window ______________________________ calendar
