Very nice!
Run like this:
Load -function { pip list --outdated } -Label "Checking packages..."Q: But you don't see the output!?
A: Run Receive-Job -Job <job#>
An improvement is to add the following lines at the end of the function:
# ...
# To get the result output from the call:
# Use "-Keep" to keep job data after 1st Receive-Job read.
$RES = Receive-Job -Job $job
Remove-Job -Job $job
Return $RES
