One of the most common template formatting styles (on English Wikipedia at least) is to use whitespace to align all the parameter values vertically. Apparently, in the TemplateData data you can set something like:
"format": "{{_\n| ________________________ = _\n}}\n"
...to emulate this style. Could we create a shortcut/alias for this similar to "format: inline" and "format: block"? While we're at it, could we have it automatically calculate the right amount of whitespace to clear all the parameter names (within a reasonable limit)?
