I liked Gamma, but I need to generate flows in presentations and I need dynamic animation. As it is, I need to generate the flowcharts out of the gamut, generate an image file and to simulate dynamic animation I have to create successive slides with the addition of details. This is very laborious and inefficient. Gamma needs to provide tools similar to PowerPoint at a minimum. I will continue using the PowerPoint because it solves my problems in a more practical way.
