I use a lot X11 Forwarding on my raspberry pi, and when I try to start graphical apps from your embedded terminal emulator, It says that it does not have any access to DISPLAY. That's normal, DISPLAY is specific to that ssh session there. That's just an example to show that if I do export CONST="This is the value", and then I start a textual app with your terminal inside in the same session to print the value of "CONST":

$ echo ${CONST}

$

If this can be solved quickly, this would help me a lot, because I need that to work in order to have pi-apps manage-daemon working inside your widget. I'm planning on making a yad wrapper for textual, but I don't have the time yet. Thank you for this amazing project !
