If possible, add info to tooltip showing your status with instance farming limits.

Keep track of the 30 instances per day and 5 per hour cap that is currently in place, or look if there is currently anything in the API to query this info from the client.

After further research I've concluded that there is no viable way of implementing this.
There are no client API calls for getting current limit count. Also there seem to be no good way of tracking new instance generation after each reset. Many other addon solutions involve the player actively reporting the reset.

The only way to get this kind of functionality into the addon I deem does not fit this project, and there are already better addons out there that focus mainly on this feature- like the following:
