Filezilla is the best windows ftp client I've used. That said, Windows ftp clients are all pretty bad. There are so many panels and c:\\ tree things and weird file labels everywhere.
Works wonderfully, I certainly got 'action'. I am in keyboard heaven! Good idea to retain Enter with the default rename function.
Good design all round. Congratulations.
Can I suggest other users try setting "Return key action" to "Edit selection / Enter single folder" in the preferences, and see how much easier it is to navigate and open files -- once you get used to the idea, that is. I suppose it won't be for everyone but worth a try.
I have to admit, once I implemented this and played around with it for a while, I did find that it's quite pleasant to use and almost, dare I say it, 'natural'
