I've found in Pte the best graphic engine and the most easy animation interface in slideshow software, however pte isn't only a picture software, we are in the audiovisual world. Actually it's very very long and difficult to synchronise objects in the animation window: there's no sound!!!! Why????? Only one audio track, it's very poor, no possibility to change sequences, no flexibility in sound fading and timing... I don't talk about sound editing and directx or vst effects , I use Wavelab for that; but it's absolutely primordial to insert real-time fading, scrubbing and overs basics functions, without that, it's a big waste of time and archaic edition... With good implementation of sounds tracks and flexibility, Pte will be the best slideshow software. Very important also is the capability of playing animated gifs and vidéos as objects. That's all!!!
