Currently, when trying to install an add-on that is already installed (with the same name), NVDA gives an error and instructs the user to remove the existing add-on. It would be good to provide an option to override the existing add-on (remove the previous one and install the "new version"). This is useful when updating add-ons, for instance. I can do that if people agree.
