jpathwatch is an open source project created by a volunteer. If it is useful to you, consider donating some money.
By donating you can help the maintainer to buy new hardware that will be used to to test and develop jpathwatch on, and to keep the developer happy. The thing needed most right now is an Intel Mac, because at this point Macintosh development consists of borrowing other people’s machines, which often is a real roadblock.
If you have any questions considering donations, you can ask them on the forum.
