pin 'em up is a tool for placing small notes/post-its (e.g. TODOs/reminders) on your desktop and organizing them in various ways (categorize, hide, upload, export, etc.). Due to platform independence, the notes can also be shared on different operating systems. It features system tray integration, freely placeable notes, many possibilities to customize the note design, (nearly) unlimited user-defined categories, fast switching between categories (e.g. "home" and "office"), automatically saving notes to a file, an open file format (XML), server upload/download functions (FTP and WebDAV), and exporting notes to a text file.
