Allow scripts to prompt for/accept input/parameters
Maybe you already do this, but it's hard to find the documentation.
We often want to run the same, fairly complicated query with different parameters, on different databases (dev/staging/prod) & compare the results.
There are a lot of ways you could support this - prompting for user input on script execution, or parameter fields above the script, or as per another suggestion, scripts that can call other scripts - so they could set initial parameters.
Or you do support something like this but it's not clear.
