I love tools and IDEs, nice work on the GUI. If you ever learn Java you could develop plugins for the Eclipse platform.

Yeah that's looking real nice now.

Are all those controls included with WinForms in .Net 2.0 or have you got some custom/3rd party stuff in there?

Most of what you see is made up with the default controls. The only more 'advanced' controls are made by inheriting from the default controls and overriding the base methods. For example, the text box is just a RichTextBox (I didn't write the translation code from text to RTF - but I'm going to rewrite it as it's horribly slow) and the file viewer on the right hand side is just a TreeView control that I've added a bunch of methods to to automatically handle the default events (AfterLabelEdit, for example, renames the file on the hard disk) as well as to extract icons.
I'm not very happy with my icon extraction code (it uses the unholy Win32 Voodoo and a lot of registry trawling) but it works in most cases.
