Support for layers has been added in Sozi 12.09 but for more than a year, I did not take the time to write a decent tutorial for this feature. A video has been available on YouTube for some time, posted from an account that I have deleted since. I will take care to put it online again soon.
So today, I am pleased to introduce the official Sozi layers tutorial.
As you can see from the Create page, there is a long list of other topics announced (most links lead to empty pages). Which tutorial should I write next?
