As a yearly plan subscriber I could easily burn my entire year budget for Kagi Assistant in a few days. All subscribers get a notification when they near the budget limit.
For monthly plan subscribers this makes sense. For yearly plan subscribers? Not so much. I propose a soft limit (by default 1/12th of the yearly budget, but it could be a setting in the future) which lets the user receive a similar limit notification when they reach this soft limit.
Have a (by default disabled) checkbox option somewhere in the Settings page which enables this.
In the future it could be extended by setting a custom soft limit value, but for now 1/12th of the year budget will suffice perfectly.
Getting such a soft limit reminds users of their (perhaps unexpected) Assistant usage. For now I have to check the usage statistics page regularly, which is something which I - admittedly - seldom do.
