Itch has made the dashboard grey for all users who share 0% of their revenue with itch.
This is a stupid practice and I wouldn't mind them asking but just doing this without any notice is annoying and counterintuitive.
For anyone still wondering, you can run a custom script on a browser extension.
-I am using "violentmonkey" extension on firefox that lets you run custom scripts.
-You can use chatgpt to help you write a script on violent monkey to disable only on https://itch.io
Just add the script and run it. Simple.. No more annoying greyscale.
