"install/reload" is not going to install your module into the main cluster folder

"install/reload" is not going to install your module into the main cluster folder, so every time i click that button, i can't find my module for another module. If i manually copy the jar to the main cluster folder, i fix my problem. I am able to "add dependency" of my module to my another module.

/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/cnd/modules

Questions:
1) Which don't provide us a mechanism to install the module into to main cluster folder when we click "install/reload in development ide" button. Search around the internet, none of the solution works. including the "nbm.is.global=true" option.
2) Why don't provide use a "uninstall in development ide button", all modules are install to "user installed plugins", and too many modules are in that so just can't uninstall one single module. OR i uninstall all module, which is too crazy.

thanks
