I put some small tools on github:
WorkList: A classical worklist with panes for new tasks, tasks in progress and done tasks. Data is saved as XML.
OpenTray: Too lazy to search for the eject button of your CD/DVD/Bluray drive? This is a small tray icon to eject your drives.
All tools are written for Windows using Visual Studio, coded in C# for the .Net Framework 2.0. Binaries are available on request.
