So I was just working on a Java project, and then these annotations popped up as I was typing. I found them to be really really helpful, but I have no idea what this feature is.
Could someone point me to the settings for this feature so I know when I can use it again in the future?
they are called Parameters hint. can disable them by going to
File → Settings → Editor → General → Appearance → Show parameter name hints.
if you go there you can configure it to match your expectations.
