What do we prefer in Kirby blueprints? .yaml or .yml?
I use .yml, probably out of lazyness, less characters.
The “official” extension for YAML is .yaml, while the standard length for file extensions is 3 characters. So I also always use .yml. But since both are supported by Kirby, that’s up to you. 
I use them randomly. But now I see this as two votes for .yml so I’ll go for that.
I always cringe at file extensions with four characters. That’s why I prefer yml as well.
+1 for .yml 
+1 for .yml (like the very old DOS format for file extensions!)
But then you would need to name your blueprints PROJEC~1.YML. Good old times…
@lukasbestle I take it you started programming while you were still in the early planning phase?
My first own PC was a my dad’s old notebook from the early 90s, so no.
