Features I want in a text editor (/IDE)

•  
• Very reactive.
• Integrates well in a Unix environment - you can run commands on files.
• Scriptable. Like Emacs, but better.
• Lets you edit files on networked machines (via ssh?).
• Files presented as a directory tree on the side.
• Can monitor files (e.g. log files).
• Read-only mode for files.
• SVN integration (i.e. being able to see older versions, svn blame, etc).
• Java (+other programming language) aware:

• Given a method name, you can see where it's defined.
• Given a method name, you can see all callers of that method.
• Given a filename and line number, you can click on the compile error to see that line number.
•
