It would be very helpful if three.js documentation could be directly accessed from Sublime Text. Currently, I keep one window open to the Three.js documentation pages. In contrast, I recently did a little work using openFrameworks (C++) in Visual Studio. There the oF library could be integrated into a project so that you could highlight an openFrameworks method and cause its basic documentation to pop up in a small window.
I realize there are big differences between C++ and JS (compiled vs. “scanned”, etc.) but perhaps the Wizards of JS and Three.js can suggest something. Fingers crossed in hope.
