Don't criticize developers too much. They are a small team of a few persons (7 incuding commercials ?) and have to cope with other developers needs and discussions to also discuss about the shared Gnutella protocol issues and network safety and scalability.

They work also with other LimeWire developers spread worldwide who send them suggestions of patches, and software behavior analysis.

And yes, they can have some vacation, and have spare time, out of their job. So things won't get fixed at your immediate needs, but bugs ARE tracked and discussed. Even a single new feature will take weeks before being implemented. For example, internationalization is working since nearly 2 months, and should have been integrated in the 2.3 release. It will probably be there in 2.4. Some bugs are really difficult and correcting them collides with other works in progress or involves structural changes.

They have priorities, and deadlines for their marketing needs. Having to pay 7 people is a huge task, and their work is honest. Open-Sourcing the software is a way to reduce the cost of the development, so it reduce the needs of aggressive advertizing, and LimeWire has already gained better support by its users because ads are carefully limited.
