I am trying to remove all window manager decorations from emacs. This works well using:
(set-frame-parameter nil 'undecorated t)
But now what I want to have is a one line (global) header line (which spans across the entire frame) which acts like a title bar. Where I can drag the frame and resize it and so on.
(set-frame-parameter nil 'drag-with-header-line t)
Works to make the header line draggable. But I so far was only able to get a separate header line for each window. But I want one global one. Also I did not find out a way to resize the frame.
Any way to do this?
