Well, this started out as an experiment but ended up as a feature. It is still not finished or tested that much, so please keep that in mind...
However, to access the feature hold Ctrl and shift and right click on the workspace background. You then have the option to grab a screenshot (.bmp) or start recording a movie (.avi). The movie can be recorded in three different resolutions (full 1024x768 and two smaller resolutions, where a "camera" window is scrolled to follow the mouse.
Both picture and sound is recorded, and a fast harddisk and a good encoder codec is required for good results.
The idea is that this feature can be used to easily record tutorials to be put online in .flv format so others can learn from them.
Please feel free to try it out !
(this feature is not enabled in the demo version btw)
