I really love File Navigator and many times I asked myself, why such a great feature isn't part of the product itself.
We are beginning the rollout of the Eclipse client in our company and we would have loved to roll out File Navigator too. But what is this? A prominent Donate button. An absolute no go for a feature in a company.
Don't get me wrong. I think it is totally OK, if you ask for support in an about window or in the online help - that's only fair. But why putting a tool under apache license, telling the community to use it and at the same time, stopping the usage by a donate button? If you don't like companies to use it, why putting it under apache license?
Add (pro) features, customization or special support and get payed for your efforts that way.
Sad to leave File Navigator out of notes :-(
