please, please, PLEASE add a feature to rename worlds!

there is a mod that does this, but the problem is, if you want to change the names again, you have to start a new save file. i want to be able to change the world names like you can change the descriptions, and i know i'm not the only one who wants this. i feel like it wouldn't even be that hard to program in if a mod was made to do it. it would give us more customization to our game and allow us to truly build our own entire world (because the game worlds are actually cities).
