Yes, this moment is clear.
I meant that values of TVs are stored in connection with templates (well, they are called template variables

) . So, if site’s user/manager need, for example, testimonials from site’s visitors to be displayed (manager chooses the good ones, of course, and put them on the site). So I’ll need to create resource for each testimonial and assign dedicated template for this type of resources to use needed TVs although I will not use this template as a template

, because I will embed testimonial somewhere on site’s homepage using snippet.
I mean, it would be handy to edit all testimonials in one place (one resource) and don’t use template where it shouldn’t be used. So, here some kind of CRUD features would be great.
Again, it’s my current nooby understanding of how MODx works, and maybe I’m wrong.
Sorry, I’m bugging you with all this questions
