Several thinks:

Hi your software seems for me very useful, what is missing please see below:
1. edit colors direct in the object
2. add possibility to display ruler to open window
3. add time scale (split hours/days/weeks/months or years) as time indicator, for ex as one axe in bottom of the screen
4. add date indicator as time indicator
5. add calendar sheet as time indicator, for ex. as week/month small sheet in the corner
6. reflector highlight effect - shaft of light
7. pip - picture in picture, for ex. combination of the same picture in one with different comments and remarks
8. snapshot camera
9. effects (fog, blur, rain drops etc.)
10.possibility to save slice by slice and make movie from the live presentation including orator voice recorder
