@Dr0p42, this feature will be helpful to create a plugin by engine as it can dynamically create commands from an input directory to find all files with commands

generate avatar by command based on image on the first cell of the notebook:

@Dr0p42, I added the plugin on each engines! Feel free to merge :)

I am not fully convinced about the way the commands are being generated automatically. Are we also planning to have a way to:

• Exclude some notebooks from being automatically added? (Removing #command should do it right)
• Having an explicit way to create a command by calling a function and specifying all parameters?

Here for example the description of the command might be a bit confusing no?

What do you think?
