I thought Delphi does that?

Ctrl+Space (identifier completion) copies the case.
Automatic recasing may be unwanted if the declaration has no casing at
all. For example SysUtils is nicer to read than sysutils.

I'm not sure, maybe jcf can fix casing.

Shift+Ctrl+E renames variables and references. It does not yet find all
references, but IMO it is already a useful tool.
