Terminal UI or live dashboards using the Floating Menu?

I was wondering if it is at all possible to have a floating menu widget display the output from a terminal application?

An example might be something like ‘btop’ or something like ‘mole status’ dashboard kind of terminal apps. See attached screenie for an example. Have tried wrapping it in the runShellScript command but I get this error:

system status error: could not open a new TTY: open /dev/tty: device not configured

interactive shells are currently not supported, I'll check whether I can add this!
Right now you would need to have "discrete" terminal commands that return the info you need and call them repeatedly
