It's not important if it is being used much or not, the important thing is we have the templates. This way anybody who wants to improve the articles can use it. It's like the summary box. Not every episode have a summary, but the box is still there.
About copying ideas, I can't say I agree with you. First, we're trying to make a good wiki and every idea is acceptable (even if it isn't ours, we're not stealing). Second, It's just too simple to call it an idea. It's only a box with text and images. We already have an evidence section in the resoloution, it just lacks the images.
