Konfabulator vs. Dashboard
Konfabulator's widgets, which I'm trying out now that it's free, tend to be a lot less slick than Dashboard's, and the UI for opening them is a lot less nice, however one area where it has a huge advantage over Dashboard is that widgets can be on the "dashboard"-layer-equivalent, or can have normal windowing behavior, always be on the desktop or always on top - your choice. If Dashboard allowed that I'd use it a lot more! Certainly any iTunes controller/status thingy needs to be available all the time, not just when the Dashboard is displayed! One wonders if Apple will ever have such a feature - the developer hack works, but only with always-on-top behavior, which I rarely want. You can run both Dashboard and Konfabulator, and I'll do that, but I'd sure like to have those windowing options for Dashboard widgets.
