This is a feature request that may be slightly out of scope of this plugin but would be very helpful for my setup (and I assume others also).

Can we have an allowance for arguments and flags to be sent into a script?

Rough implementation idea:
Via the UI, this could be done with a popup asking for args or possibly a dropdown of options. This would require a method to define these - possibly a seperate file?
Via the exec script, it could split the "script name" by space - item 0 is the actual script name and items 1+ are the args/flags.

My use case:
I use folder view and compose manager. I'd love to call a use script to up/down/update a compose project using the custom commands in folder view which uses this user scripts plugin. I'd also like to have a script I can run on a schedule to do the same. Ideally I just want 1 script to do this for all of my compose scripts, but at present, I need 1 script per compose project. Having args I can send to the script would fix this.
I'm sure there are plenty of other scripts that would benefit from this.

When managing docker-containers from within a docker-compose file it would be awesome to define a docker-folder via lables.
