It's excellent piece of software. I started using it when debugging
remote/server things, and ended with using eveywhere.

It has two drawbacks: it doesn't remember your commandline, watches and
sizes of panes, and has ugly default colour scheme.

Few years ago, I used Eclipse+PyDev, but I was tired with recurring
strange problems with Eclipse, which eg hanged until I reinstalled
eclipse or removed workspace metadata.
