APEX Builder Extension by FOS Autor: FOEX

The "APEX Builder Extension by FOS" enables you to edit static application, workspace, and plug-in files, directly in the APEX Builder! With seamless integration into the existing builder screens it will vastly improve your development speed & workflow when dealing with JavaScript, JSON, and CSS files.

It uses the same powerful code editor as the one behind Visual Studio Code and allows you to edit multiple files at once, in split screen, or optionally in full screen. You can create files and save changes without submitting the page, giving you that "native programming" experience.

Other notable features include: JavaScript file minification and Less CSS file compilation.
