I would like to thank Drew D. for directing me to the mRemote tabbed multi-client utility, it is truly great! Not only does it do tabbed PuTTY sessions, but also Telnet, HTTP, HTTPS, Citrix, RDP, VNC, RAW, and Rlogin. It also supports arranging connections by folders and allowing new connections to inherit the settings from the folder they are placed within for faster use. There is also a portable version for those that want to run it from a USB stick or memory card. Check it out!
If anyone else thinks there are better free utilities out there please feel free to post a comment telling us about it/them.
