FileTool

This was a project I started on quite a while ago in order to make editing work in the shell environment that I work in at school easier through a graphical environment. Now, granted, this is nowhere near done, and I do have a lot of work left to do on it, I think that so far, I've done a pretty good job. But I'd like to know what you think.
