oldmanyellsatcloud.gif But seriously, it's a silly limitation from a bygone era. Why should we adhere to it? Why should we have to remember these things? Some of them are easy to remember, but even less technical users change their workflows from time to time. Sketch uses ".sketch" as its extension. Should they have gone with something ".skc" as their extension, just because that's *the way things are done?", even though the application only runs on the latest version of an operating system without that primitive limitation? Even with Markdown, most people use ".md", but Gruber has expressed ".markdown" as his preference because the limitation doesn't really exist.
