PuttyLauncher is a plugin for WinCommandPalette.
This plugin will load all your saved PuTTY sessions and create a command for them. Also it creates a command to load all your private keys into pageant.
You can also create your own putty commands for SSH, Telnet, Rlogin, Raw and Serial.
Download the latest release and extract the .zip file. Copy the PuttyLauncher directory into your WinCommandPalette directory and finally restart WinCommandPalette.
To reload newly saved sessions you have to restart WinCommandPalette, as there is no API yet to add/remove commands.
