My main motivation was the get the rightclick "new File" as in ftp programs or on windows.
But yes I guess in general a shortcut may be faster but lets say one creates macros for multiple people that don't want to learn a loud of shortcuts.
Also if that would work folder/filetype specific this could be massively handy. Lets say if you rightclick on a image you get for example "Convert to CMYK", "Resize to twitter format", "Move to images folder". In that case is a visual dialog more elegant than a shortcut in my opinion.
What I also tried out is to trigger them through an applescript app in the top bar of the finder. Still testing things out a bit not quiet sure where I should trigger my macros =).
I've changed my copy of the script in post #6 to create new text files from scratch, so the creation and modification dates match when the file was created.
I've left the dates of the other template files alone, so they reflect when the template was created/modified – although it wouldn't be too hard to update these to NOW() (when the "new" file is created) – and that might be the better choice for some users.
