Modifier Modifier Plugin allows you to quickly change the modifiers (static, final, etc.) of one or more fields, methods, variables, and classes using hotkeys.
The only change in this version is that you can now select multiple fields/methods/variables to mass-edit modifiers of many fields, methods, variables, or classes at once.
To make some fields non-final:
Select from anywhere on the first line to anywhere on the last line, and press AltShiftF.
