ResourceBundleEditor currently offers a function to rename individual keys or even groups of keys.
This is a very *dangerous* operation, since it does *not* rename references to these keys.
Additionally, once a key is renamed, it is hard to find the corresponding references. This problem multiplies when renaming groups(!)
Luckily I tried this function on a single key, but I'd have suspected that an editor tailored to ResourceBundles deals with such a functionality in a more complete way.
I am currently in the middle of refactoring a mid-sized application that has a grown collection of resource keys, so I'd certainly need a simple way to refactor resource keys, and this editor would be an ideal solution...
