I welcome anyone who wants to to register an account and start editing the documentation page. The entire homepage is basically a Wiki which anyone can edit (except for a few pages, which are write-protected). So any user can write some documentation, maybe add some screenshots or provide some installation instructions that are missing.

Since I've got only limited time to work on this project, I prefer to focus on making the program so easy to use that documentation should not be necessary ideally (of course that's not entirely possible).

Do you mean elevation over time and speed over time? As far as I know GE doesn't provide those views. Additionally the .kml files I produce don't contain enough information for those kind of views (they contain only the coordinates, no timestamps and speed information). There is a tool that I use which shows those kind of views for any .gpx file (including the ones produced by bbTracker): GPS-Track-Analyse.NET 4 Unfortunately it's german and it's not open source software (it's free for personal, non-commercial use, 'though).

I've been planning to produce a client-side companion to bbTracker (bbTrackViewer?) which would provide such a thing, but currently I don't have the need for it, bbTracker is taking all of my free time and GTA provides this tool for me, so the chances of this piece of software beeing written "Real Soon Now" are pretty slim.
