[Feature request] Choose the display used #20

I was wondering if you could add the ability to choose the display the message is shown on?

I would like to be able to trigger a screen message on a device I am connected to through SSH, but i get this error (sm:1091950): Gtk-WARNING **: 13:30:46.306: cannot open display: I assume this is because it's not trying to use the machine's actual display and I imagine being able to choose the display manually would solve this. Running the same command locally works properly btw

Do other gtk-based applications work in that setting?

I assume you are facing the more general question of setting the DISPLAY variable, which then screen-message will use if set correctly.

I actually already tried this but apparently I did something wrong last time. Thank you.

If anyone else happens to have this 'problem', in SSH, I just ran export DISPLAY=:0 first and then it works as desired.
