Thought I'd tell you about this ux/bug -- you can't change the name of your repo in "Repository details" if it's the same name.
You get: "You already have a repository with this name."
But you should be able to if it's the same repo!
For example, if I want to change my repo name from "mycode" to "Mycode" (i.e. Capitalise it) you will get this error.
Thought I'd share!
