It would be great to store interaction states in the cookie,
for example: someone clicked on a block article that has a "new" tag, this tag is removed and when the user visit the same post again, it's not show.
Also, it would be nice if that it's possible to send that saved cookie to some custom code. Let's say user clicked on a button , and then I hook this cookie to a custom audio player script, which knows either to keep playing the audio or to pause it.
And then it would be great to link it with this GDPR idea, to be able to opt in or out of specific cookies. https://www.amazon.com/Neewer-Microphone-Isolation-Absorbing-Broadcasting/dp/B07N3SX1RL/ref=sr_1_18?dchild=1&keywords=table+shock+mount+mic+stand&qid=1605780952&sr=8-18
And also to integrate an in built option for Do Not Track.
