Well, thank you for your answser. But changing caret width from Windows Control Panel has global effect, which is probably not desirable for a Windows user. So I hope I can customize caret width according to different file type(called Configuration in EmEditor).
As I know, Windows provide CreateCaret API which allows application to set the caret width(the nWidth param). Can EmEditor consider letting its user customize it?
I could, but Windows XP/Vista design guide tells that we should use the control panel settings. In order to get Designed for Windows XP logo, I needed to use the control panel settings.
