OpenSource Multitab Remote Clients

I know that many sysadmins prefer the unix console to connect to other hosts. For those who come from the windows side, there're some options, besides the well known putty.
One of the things that i miss from putty is the multitab feature (that can be found in other licensed software). I did my research and i found a couple of good clients, that  i will like to share with you
Most of them are based on Putty and others don't :)

MremoteNG

MTPuTTY (Multi-Tabbed PuTTY)

http://ttyplus.com/multi-tabbed-putty/

Terminals

Many of this clients share some features:

- Import/Export of configuration files
- Folder/Group organizations of the hosts
- Support of several connection protocols  (SSH, RCP, TELNET, etc)
