I’m now using Bike regularly to work with some of my markdown files, but it is cumbersome to manually change .txt to .md for all my files. All my other apps (Obsidian, Nota, MMD5, Typora, etc.) use the standard extension for markdown files. It would be logical for Bike to include this and significantly improve its ease of use.
I was a long-time user of FoldingText. Bike is a great successor to FT. Keep up the good work!
