Putty - but better

Most people will have likely come across PuTTY, the Open Source terminal emulator. It's quick, easy and pretty ubiquitous in it's accessibility (to devices).

One annoyance is that it is a single-window application, and that firing up multiple SSH or Telnet sessions created lots of individual windows. In these tabbed-app days, that seems a bit Windows95.

However, this somewhat stodgy way of working can now be relieved with the use of an application called PuTTY Connection Manager, which can fire up individual SSH or Telnet sessions as tabs. Additionally, your saved PuTTY sessions can be presented as a folder tree, which simplifies opening the individual sessions.

It still uses PuTTY as the underlying engine, but overlays the Connection Manager to give an easier working experience.
