How to make .md the default extension in iA Writer? [TWEAK]
In a recent update of iA Writer, the application changed the default file format from MD to TXT. Since I use iA Writer to write in markdown, as I assume most of you do, this change came as a bit of a nuissance to me. Furthermore, there is no options in settings to configure. The only option is to start writing your file in .txt format, and later rename it to .md.
