A simple confirmation popup is fine by me @xiota, as @eht16 said, please accept the decision.
@eht16
No space here with my GTK theme with a default config:
Yeah, differing themes, oh well it was a thought.
As you say, its dangerous, so its likely to only be used rarely. Note neither Eclipse nor Vscode (yes I added it to my menagerie) have a replace in session or equivalent, so its not like users coming from some other editors are going to expect it.
Therefore a simple popup is fine and lets get on with important work.
