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.
