Hope this finds you well. I was wondering how to check my attempts for specific mounts/pets. Is this possible? If not, can this be added?

Do you mean attempts for items you are currently tracking, or an overview of all attempts you've had in the past? You can check the Options UI for each individual item, but it's probably not very convenient.

I could try to find a way to display overall attempts, perhaps, but it's difficult adding new features on top of the convoluted codebase. Plus, I don't really have any time to do much except make sure the addon is still functioning in a basic capacity.

I'll consider this a feature request, somewhat related to #172, but I can't promise I'll have time to add new features anytime soon.
