This is really cool! I might use this to help plan some of my 2025 vacations

Some suggestions for useful features:

- Ability to customize the work week. I only work Mon-Thurs, which will greatly affect the optimal solution

- Add arbitrary holidays in case the company gives an extra day off, this would nicely complement the existing feature to turn off some holidays

- Select an arbitrary time frame less than a year long. This would be helpful especially to plan end-of-year vacations

- In addition to or instead of the previous point: input what vacations you already have planned. Obviously I can't always take only the most optimal vacations, but I could potentially make my existing ones more optimal by extending them in some cases

Thanks for sharing it! Really cool idea, I've only done this kind of planning ad-hoc in my head, it never occurred to me to solve it exactly
