Erlybird looks very fine while working in Netbeans. Unfortunately Erlide (the Erlang plug-in for eclipse) wasn't that smooth.
The strange thing about the plug-in settings is that it shows itself like if it would be a JRuby plug-in:
What could be done better, I think, is when I run a script, instead of the erl interpreter I could choose a function to be used to start the script. So it could look like any other program I'm running in IDE.
