Overview
Pterocos and PawPause serve entirely different purposes. Pterocos is a web-based development environment for HTML, CSS, and JavaScript, featuring a Monaco Editor, live preview, and an AI coding assistant. PawPause, on the other hand, is a tiny macOS menu bar app that detects when your cat walks on the keyboard and pauses input system-wide, ensuring your work isn't disrupted by furry friends.
