I appreciate that you took the time to provide feedback on TimeLapse. Thanks!
The capture speed problem has been discussed in other threads in the forum. Basically, there are a few iPhone OS factors that I have no control of. With regards to your concern of waiting for the UI to load up. As far as I know, the UI can only take one photo per "showing". I have to dismiss and then re-show it to take another photo.
Finally, what did you have in mind for integration with the video capture capability. Can your provide an example of how you would use video in the context of TimeLapse?
