Hi,
The user manual is at:
http://www.topofusion.com/manual.phpI think perhaps your confusion is with this list of features:
Advanced features (described on separate pages):
3D visualization
The logbook feature
Climbing Analysis
Difficulty and Effort index
Image Processing / Combo Maps
PhotoFusion - Auto placement of photos on tracks
Simplifying and Interpolating Data
Multi-Track Playback
Each of those goes to a separate page, so it's not just a list of features, but a list of links to pages explaining them.
In any case, glad you like the program and thanks for registering.
