Awesome. When I moved to linux a few years ago notepad++ was one of the harder apps to find a replacement for. I ended up sticking with Kate Edit: Kate is great, give it a shot!

Looks like an IDE more than a notepad, with the side bar browser, but then I suppose it's a small step up from NP++ (with syntax highlighting and ftp^W git support already built in) to a fully fledged programming environment. Spotted the all-important keyword "vi bindings" also. I should give this a try!
Bit sad it won't work on remote systems (without inefficient X forwarding at least), but I've been looking to try out a new editor and e.g. not having to deal with things like O timeout (apparently that looks indistinguishable from the start of an escape sequence and so the command line has to wait to see if the rest of the sequence follows) has advantages as well
