Rails Shell View

The Rails Shell view is a good example of why I prefer RadRails over other existing IDEs. Someone asked in the Aptana forums if RadRails could incorporate a nice feature he saw in a different IDE. Chris Williams, the lead developer of RadRails, asked him to enter the desired features into the Aptana Issues Tracker, where you can report any bugs or ask for any functionalities you would like to see in RadRails. Some months later, in RadRails 1.0, the Rails Shell view was already available.

From the Rails Shell view, you can have the best of two worlds: the power of the command line and the ease of use of a development IDE. You can basically run rails-related commands from a command shell with content-assist.
