Having been inspired by the icons for LWM, LWC, Neverland, VE, and the generic world icon, I propose that the remaining world icons (FTL, Wonderland, Oz, Kansas, 1920E, LUS, 19CF) be given a round border. This will introduce some continuity to the icons to easily identify them as relating to a world. See some mockups here .
Separate to the above proposal, I would also like to suggest a system for NEF and all future worlds relative to the post-soft reboot of S7. Unlike the World icons for S1-S6 with the icon in white space surrounded by a circle, we could reverse the colours and have the symbol as white space with the circle filled in, like the one for Seattle. A small but a tidy way to distinguish the prime series worlds from the post-soft reboot.
Disagree with both, especially the second one. This is not a good idea.
We should absolutely avoid making any difference between seasons, they are ALL seasons of the same show. Especially with all haters going around internet, if we begin to show difference between seasons... Well, I don't think it could result in anything positive for the wiki and our image.
And I don't see the point of making all icons with round borders, all icons are fine as they are. That's just being nitpicky. And the round border is quite ugly when the background of the icon is transparent, already tested it.
