Everything I've ever wanted to configure or customize about how it works, it can. Yet it's not bloated with a bunch of un-necessary features. It has exactly what I need in an SSH and SFTP client, works every time, never crashes, never gives me trouble. Incredibly intuitive, too. Everything is where I'd expect it'd be. Simply brilliant. -- Kelvin
