I am happy to give some feedback when I get to use a new (to me) feature but I am not sure that I am feeling up to submitting a full documentation description just yet. Meanwhile, I hope these comments help.
I installed v3.2.0.0 and tried the Maps/Lifelines feature. It is not yet documented in detail but everyone should give this a try. It is easy to use.
There are a few improvements that I would like to see, if possible, but otherwise it is a great 'time waster'.

I have spent over an hour writing this post while investigating the capabilities of this part of FTA.
Most of my past relatives have only a few Residence Facts so I added several new ones (is that grammatically correct?) for my own instance although not strictly relevant as far as any census is concerned. I was very impressed with the way that my life movements were then displayed across the world. This feature makes it much easier to appreciate where families moved from and to. The main limitation seems to be with how well Google recognises each address. For instance, why is Chester, Cheshire, England only partially resolved? In other places I was reminded just how important it is to include the country in every address, otherwise St Paul, Shadwell, Middlesex is resolved to be Paul Street, Lexington, North Carolina! Another justification for using FTA to highlight data omissions - thank you Alexander. I also thought it funny to see Scotland become Achamore House in Loch Tay!
I immediately noticed the name of the subject individual being displayed upside down, depending on the associated data, but suspect that the display of that name is probably outside of the FTA program's control. At first, I also wanted an indication (in the map's title?) of just where was being displayed as I had no idea where Mouldsworth was until I had zoomed out quite a distance. However, I then noticed the data facts under the map which could supply that appropriate information. Perhaps a note about that could be included in the documentation when it is extended?
The lifeline is displayed with a green dot at each end (start and finish?) but the relationship to each displayed fact is not clear where there are many locations displayed which the viewer is not familiar with. For instance, could extra relevance be added (easily?) with intermediate 'dots' and an on-map label or fact highlight when the pointer hovers over each such location???
