I am the author of the following fine Mac OS X applications and utilities:

FolderGlance	Screen Sieve
FolderGlance is a utility that extends the Finder with the ability to dig into folders from the Finder's contextual menu, and much much more.	Screen Sieve enables you to search in any window on your desktop, highlighting all matches as you type.

Spaces.. Spaces.. Spaces..	Universal Back Button
Spaces.. Spaces.. Spaces.. is an attempt at fixing the new Spaces feature in Leopard. Very hacky.	Universal Back Button brings you back to the application where you clicked that link or opened that file.
