CoreRPG+ Extension: Has Initiative Indicator
If you're having issues with extension please read this post first on making sure you have correct extension installed.
This extension will work with any CoreRPG based ruleset (Except AD&D Core since it's included). Requires CoreRPG 3.3.12+ to function.
What does it do? This extension, when enabled, will show a Crown above whatever token currently has initiative.
Why? Well, the tiny white ring is way to subtle for me to notice at times and right now there is no way in the API to tweak that (make it bigger or a different color) as far as I know. This has something to do with scaling and token/image sizes but... either way, this was my way to resolve it for my own use.

Cycle through initiative in the CT and you'll see this. As you can tell the white ring is really narrow on this token.

Here is another view, this one you can see the bigger ring.
