This is a simple .Net 2.0 application, written in C#, that allows you to log the tasks you work on on a daily basis.
It sits in the system tray, and starting or stopping a task takes just a click (and optionally entry / confirmation of the task being started / ending).
Logs are stored as daily XML files in a specified folder, and that is where it's not quite "Usable" yet:
- The files are opened/saved automatically, not always including the latest changes
- categories of tasks don't work yet
- there is no practical way to look at previous days' information
Github makes this stuff so easy, it's tempting to put even embarrassing code online:
