Hello there!
Well, I'm not exactly an admin or something in this wiki, but I wanted to do the following things to the wiki's templates:
Update the main page to be better on mobile/SEO.
Move Template:Generator to Template:Infobox generator to be consistent with the other infobox templates
Change categorization of the templates (e.g: Templates/Infobox becomes Infobox templates)
Update the "documentation" (instructions on how to use them) to be useful for editors
Update the navigation boxes, i.e the {{Tech Tree of Life}} to use {{Navbox} and fix links.
Fix some formatting of the pages
And some more stuff that I haven't mentioned, but may implement.
So just asking, but is it okay if I do the mentioned changes? If I do this, it can help for the long run of the wiki, since maintenance would be easier.
(I might add some content to the pages too, but I prefer maintenance stuff like these)
