Can't find Wang Editor

Hi Bjorn,
thank you so much for this amazing software.
In lockdown, I have started playing D&D with my daughter, and recently came across your map editor, which makes it so much easier and engaging to create maps.
I am starting to develop fairly large and detailed maps now and am trying to understand you software better. In particularm I’d like to start using the wang tiles feature, but I can’t seem to find or access the wang editor function on my gui. I am using 1.0.3 on linux mint 19.3 cinnamon.
Any advice?

I think I may have resolved it already by installing the latest version
