A fork of PuTTY v0.61/portaputty v0.60 - it's PuTTY with settings saved to a .putty directory in the same directory as the PuTTY executable, rather than to the registry.
I take zero credit for this, all I did was apply some of the changes from portaputty to the latest PuTTY code and built it with VS2010 :-)

"Potato Salad" - portaputty.
