Sailboat is what I use in my daily development with Sails. It allows you quickly jump to a specific action from the routes.js file, visit section of the Sails documentation relevant to you from the command pallete as well as launch Sails development server.
Before Sailscasts: You wonder where to learn and master Sails to a pro level for your work and personal projects. Endless google search and hunting for answers across the Sails documentation for how to get things done. After Sailscasts: Master Sails to build your ideas, products and businesses.
Say ahoy to guppy - the needed tinker tool for every backend Javascript developer. You will find yourself having this desktop app open as you do any backend Javascript development.
