I've used them a few months ago but they suddenly stopped working and caused several kernel panics (maybe because it isn't really made for OS X Lion) so I bought Transmit. It's working now but I would like to see a solution integrated into ST2.
I have no problem with that but Mac and Windows-Users are forced to use or even buy software to do that. On Windows most of them aren't working so well and on Mac OS X everything is more expensive due to the Mac App Store.
In Notepad++ S/FTP is natively integrated into a sidebar that can be opened. It feels just like a local filetree in Sublime Text 2.
The plugin is crap. I would like so see native integration like in Notepad++ (although it's handled like a plugin there).
