I find the Toolset Module Manager is now being the Legacy plugins, may I know whether it is still available for new version of WP or there is another plugins to be the substitute?
Do you mean the legacy plugin is just using the legacy views/content templates and it will be developed in the future?

I mean to say the views/content templates created using blocks - the import/export for that using Module Manager plugins is not supported.
We will try to improve but in future and there is no ETA on it.
