It's a small thing, but it would be nice if a site running locally could use a different version of a favicon, to make it easier to separate local and live sites visible in browser tabs.
I had in mind a really simple implementation, where a local favicon would just have "_local" appended to the name of the current theme favicon, so:
Then, if the site is running locally, and if a local version of the favicon exists, use it instead.
My question - what's the best way to implement this? Also, what would be a good way to check if a site is running locally?
Thanks for any ideas, code, or pointers.
