This webtrees module extends the slide show in such a way that, in addition to the names of the people, their lifespan is also shown.
It registers a custom view for the slide show, which is based on the original view and just adds the lifespan output.
Unzip the files into the folder of your webtrees installation.
You need Composer and the PHP xdiff extension to build this custom webtrees module.
composer update
composer build
The build
command creates the custom view by patching the original view and then packs all relevant files into a zip file.
