Cool!
Since I was tired to hack plain text files when trying to port some stuff to Squeak I've put a FileContentsBrowser on the UIUC server. The idea is that while the class browser is a great tool it can currently not be used to give us a "structured view" on a (syntactically correct) Smalltalk source code file. That's exactly what the FileContentsBrowser is doing. It just scans the file and you can browse the classes and methods of this file _without_ having to actually install it.
I found it very helpful when porting stuff even though it's very simple at the moment (you cannot modify anything). Also, I like it much more to review changes than the current change list. Another reason I put this onto the server is the recent discussion about where to put applications such that people are aware of it. One could easily think of adding some ftp support to it such that you can browse the contents of any application on any ftp server around the world.
Just try it! Andreas
