Markus, your and my English are too different
, I don't undestand you... sometimes.
Wir sollten auf Deutsch sprechen
What I meant was simply an "answer" to:
Deleting code modules is something that should be done really carefully
This is true; but...
If I'm not mistaken, I have not investigated much, when you rename a module, a copy is created with the new name and the project will use this new copy; so just ask the user if he wants to
delete keep the original file - setting the button [Yes] as defaut should be enough.
Um... No, everything is not so simple, given the matter of shared modules (with also the latest news that I still have to read well).
