Would be great to select a bunch of files and change their extension to something else

So why don't you do it? Select them, context menu, Rename Special, Search and Replace, enter e.g. ".old/.new".

But rethinking extension replacement I believe I have to add a special command, because currently if you rename *.htm to *.html then any existing *.html files would be renamed to *.htmll. Not good...
EDIT: Also you cannot change a bunch of different extensions to one extension. So: a special command is about to come...
