PHANBOI  The TimeLog 4 betas are a promising upgrade to the excellent TimeLog 3.

This is a tool that focuses on doing useful work for you with little bloat.

What it does well:

- Automatic timer logs your work in iCal by client, project and category.

- Automatically applies billing rates that can vary by category or by client.

- Supports surcharge rates for special work.

- Create and complete ToDos from any application, smoothing your workflow.

- Reports quickly time and billing amount by client and project

TimeLog 4 required a major rework to adapt to the changes and Leopard and this shows in the differences in the application.

- New look, more colourful dialogs

- New Timeline view with handy editing features

- Enhanced export formats (xml and csv)

- Network integration through CalDAV and HTTP POST of XML data.

- Smart lists allow customizing the view for your needs.

- Print reporting moved into the print dialog.

The developer is very responsive and focused on constructively responding to client feedback.

I'm looking forward to the final release.
