Can I always show window number, even when there's only one window in a frame?

[Thomas Heartman]

Hi,

Is there a way to make the mode line always display a the window number, even when it's the only window in the frame?

I use EXWM as my window manager and juggle multiple frames with an arbitrary number of windows. However, when a frame has only a single window, the window doesn't display its window number, so I need to manually figure out which window is the previous and then add 1 if I want to find the shortcut to jump to the window.

Is there setting to always show the window number in the mode line, even when there is only a single window in the frame?

Thanks for any help and for the package itself!
