After participating in a NetBeans Platform Certified Training by the famous NetBeans guru Geertjan Wielenga I decided to build a plugin to help me and my team find things easier. It's also my contribution to achieve the next level of certification after this course.
Question to answer: Where can you find the Java file that controls the code folding [+] in your NetBeans IDE?
My guess is that it's maybe one or two persons yelling out: "org.netbeans.editor.CodeFoldingSideBar.java" in "editor.lib module", while the rest of us will say .. ehh .. daa.. editor some thing .. maybe, only 26 modules to look thru...With this small tool started you just put the mouse on the components to find the needed answer:
