hey, guys. I support this in PR #203

+1 and (or alternatively) it would be also great if there is the option to show a short description/hint for every parameter.

It would be also something absolutely fantastic to build this list from a result of another script, for example

[[snippets]]

description = "Activate gcloud configuration"
command  =  "gcloud config configurations activate <param_command=gcloud config configurations list>"

Then in execution window a small list to select out of the param_commands.
