HI,
I like this Widget too. And i second some of the wishes:
- adjustable recording level (it ist faar too low)
- noticeable recording status
- autostart or "button" in the telephone screen
- what about mounting it as a shortcut instead of a widget?
But again, really nice and useful.

Nice idea, but unusable in reality:
1) There is no indication whatsoever if the program has been triggered (e.g. accidentally). It will then record until it has drained the battery in a surprisingly short time.
2) It drains your battery. This was the first time ever that I heard the power alarm sound of my N900.
3) The icon is so small that it is impossible to drag it around without the stylus. Since it is only marginally larger than its close button, dragging usually removes the whole widget.
